A diver jumps off the diving board at 2.5 m/s. Assume the diving board is 2.5 m above the water surface in the pool and the diver has a tiny forward velocity so she could clear the board in her way down and hit the water feet first, how long will it take her to strike the water surface? You can set the final position to be zero.

You are walking around your neighborhood and you see a child on top of a roof of a building kick a soccer ball. The soccer ball is kicked at 50° from the edge of the building with an initial velocity of 10 m/s and lands 20 meters away from the wall of the building. Which equation will allow you to solve for the amount of time the ball is in the air? Hint: look at your givens in the x-direction. Group of answer choices A. vfx2=v0x2+2axΔx B. vfx=v0x+axt C. Δx =v0x t + ½ axt2

An Olympic diver is on a diving platform 9:40 m above the water. To start her dive, she runs off of the platform with a speed of 1.18 m/s in the horizontal direction. What is the diver's speed, in m/s, just before she enters the water? m/s Additional Materials

Alice shoots a pebble horizontally with her slingshot from a window that is at a height H and it lands a distance D away from the building. She then shoots a pebble with the same initial velocity from a different window, but this time the pebble lands a distance D/2 away. How high is the window from which Alice takes the second shot? A. 4H B. 2H C. H D. H/2 E. H/4

An airplane takes off and flies upward at an angle of 21° with a constant speed of 262 m/s. While the plane is flying upward, a piece of the engine falls off when the plane reaches a height of 860 m. a) How long does it take the piece of the engine to reach the ground? Give your answer in seconds. b) What is the horizontal distance covered by the piece of the engine before it lands? Give your answer in meters.

Several people stand on a bridge over a river.  The bridge is not level, so the people are all different heights above the river.  Each person throws a stone to the river. a) The first person is 26.8 m above the river and throws her stone with a speed of 16.6 m/s at an angle of 6 degrees to the horizontal (positive degrees are above horizontal, negative degrees are below).  How long does it take her stone to hit the water, in seconds? b) The second person is 19.0 m above the river and throws his stone with a speed of 17.1 m/s at an angle of -21.4 degrees to the horizontal (positive degrees are above horizontal, negative degrees are below).  What is the range of his stone, in meters? c)The third person is 9.1 m above the river and throws their stone with a speed of 6.5 m/s at an angle of 9.3 degrees to the horizontal (positive degrees are above horizontal, negative degrees are below).  What is the speed of this stone (in m/s) just before it strikes the river?

Two shuffleboard disks of equal mass, one orange and the other green, are involved in a perfectly elastic glancing collision. The green disk is initially at rest and is struck by the orange disk moving initially to the right at vOi = 5.80 m/s as in Figure a, shown below. After the collision, the orange disk moves in a direction that makes an angle of ? = 34.0° with the horizontal axis while the green disk makes an angle of ? = 56.0° with this axis as in Figure b. Determine the speed of each disk after the collision.

After discovering that two hikers have been stranded on Devil’s Thumb Pass, the Colorado Search andRescue team sends out a plane with supplies for the hikers. Because the hikers are in an isolated location, theplane has to drop the supplies as it fies overhead (see Figure 1). If the plane is 235 m above the hikers andhas a horizontal speed of 200 km/h, how far away from the hikers should the supplies be dropped if they areto land at the hikers’ location?

John kicks the ball and launches it into the air with an angle of 32° to horizontal. If it's initial velocity is 12 m/s, what is the maximum height the ball reached?

The first active volcano observed outside the earth was discovered in 1970 on Io, one of the moons of jupiter. The volcano was observed ejecting material to the height of about 3x105m. Given the acceleration of gravity on Io is 1.8 m/s2. Find: a. The initial velocity of the ejected material. b. What is the velocity at half that height?
