Chapter 3, Problem 56AP
Antlion larvae lie in wait for prey at the bottom of a conical pit about 5.0 cm deep and 3.8 cm in radius. When a small insect ventures into the pit, it slides to the bottom and is seized by the antlion. If the prey attempts to escape, the antlion rapidly launches grains of sand at the prey, either knocking it down or causing a small avalanche that returns the prey to the bottom of the pit. Suppose an antlion launches grains of sand at an angle of 72° above the horizon. Find the launch speed v0 required to hit a target at the top of the pit, 5.0 cm above and 3.8 cm to the right of the antlion.

The earliest drop towers were used for the purpose of making lead shots for muskets. The procedure
involved releasing droplets of molten lead from the top of the tower. As the droplets of lead fell through
the tower, they formed a spherical droplet. If given enough free fall time, the droplet of molten lead
would solidify to form the perfect spherical shot. The tallest of these drop towers in the United States
was a 230-foot tower built in Baltimore.
Suppose that lead free falls through a drop tower for a distance of 63.9 meters
a) Determine how much time (in seconds) it takes the lead shot to fall this distance of 63.9 meters.
b) Determine how fast (in m/s) the lead shot is moving after free falling for 63.9 meters, right before
hitting the ground
When the red kangaroo of Australia is moving at full speed, it can bounce at a speed of 8.5 meters per second, at an angle of
45 degrees above horizontal. Assuming the kangaroo is bouncing on level ground, what is the kangaroo’s hang time in the air during a single bounce?
For a forensics experiment, a student decides to measure the muzzle velocity of the
pellets from his BB gun. She points the gun horizontally. On a vertical wall a
distance 47.3 m away from the gun, a target is placed. The shots hit the target a
vertical distance 0.10 m below the gun's barrel. What is the initial speed of the
pellets?

- Georgia, standing on the back of the pick-up truck, wants to throw her last piece of balut to her mortal enemy, Emma. before the truck started moving, the two women are separated by a distance of 2 m. For two seconds, the truck uniformly accelerated until it reached a velocity of 4 m/s which it then maintained. With hatred, Georgia throws the last piece of balut with a velocity of 12.5 m/s at an angle of 40° from horizontal, measured relative to the truck. If she makes the throw 2.8 seconds after the truck started moving, will she be able to hit Emma? Note that Emma is at rest due to exhaustion from their earlier fight and she cannot dodge the balut.

The pole has a lake of 15 8 feet and once the athlete releases the pole he will find a mattress 2 feet high, 10 feet wide and 16 feet long, which protects him in the fall. If an athlete lets go of the pole when it was 13.7 ft above the ground with a speed of 15.7 ft/s at an angle of 73 degrees. Enter the horizontal distance that the athlete will travel with the indicated conditions, add the units in the resultarrow_forward

A pool shark places a ball on the table, hits it in what appears to be a random directon, and yet it bounces off the edge, falling directly into the pocket.

In the story, David uses a sling to increase the speed of a projectile (in this case a rock), striking Goliath in the forehead and killing him. O The type of sling often used in such combat consists of a long strip of cloth with a pouch halfway down its length. The rock is positioned in the pouch, with the warrior holding both ends of the sling. By whirling the sling in a horizontal circle, a warrior can release one end of the sling, thereby allowing the projectile to fly in a straight line at high speed. Historically, warriors and hunters typically used a vertical circle, but the circle used here is horizontal for simplicity. In this problem, assume that the sling, when unfolded, was roughly R = 5.54 ft in total length and that the rock weighed a half a pound. If David whirled the sling such that the sling was at an angle 0 = 4.73° below the horizontal, with what…arrow_forwardA mortar is like a small cannon that launches shells at steep angles. A mortar crew is positioned near the top of a steep hill. Enemy forces are charging up the hill and it is necessary for the crew to spring into action. Angling the mortar at an angle of 0 65.0° (as shown), the crew fires the shell at a muzzle velocity of 148 ft/s. How far d down the hill does the shell strike if the hill d subtends an angle o = 37.0° from the horizontal?

- You need to get into your fourth-floor apartment, but you have forgotten your key to the main ground floor door of the building. You call up to your lazy roommate to come down and let you in, but he says he will throw the keys down to you instead. The window that he throws the keys out of is 13 meters above the ground, and he chucks them with a speed of 2m/s at an angle of 20 degrees above horizontal. The acceleration due to gravity near the surface of earth is 9.8 m/s?.

The ball follows the standard path of a projectile, first rising as it passes over the net, and then descending. The opponent receives the volleyball 1.1 seconds later at the same height (2.4 metres above the ground), and at a horizontal distance of 13.5 metres from the server. Answer the following questions assuming there is no effect of air resistance. When the ball was received by the opponent, the horizontal component of velocity (in m/s) was? The vertical component of velocity at take-off and impact (in m/s) can be solved by recognizing that the vertical component of velocity at the point of maximum height in the trajectory of motion is (in m/s)?arrow_forward
