During a recent winter storm, bales of hay had to be dropped from an airplane to a herd of cattle below. Assume the airplane flew horizontally at an altitude of 180 m with a constant velocity of 50 m/s and dropped one bale of hay every two seconds. It is reasonable to assume that air resistance will be negligible for this situation. About how far apart from each other will the bales land on the ground? O 300 m O 180 m 100 m 50 m

Imagine that you hit a ball at ground level and send it toward the wall with a speed at 18 m/s at an angle of 32° above the horizontal. (a) How long does it take for the ball to reach the wall if it is 3.8 m away. (b) How high is the ball when it hits the wall?

1. A physics book slides off a horizontal table top with a speed of 1.10 m/s. It strikes the floor in 0.350 s. Ignore air resistance. Find (a) the height of the table top above the floor; (b) the horizontal distance from the edge of the table to the point where the book strikes the floor; (c) the horizontal and vertical components of the book’s velocity, and the magnitude and direction of its velocity, just before the book reaches the floor. (d) Draw x-t, y-t, and graphs for the motion.

An archer shoots an arrow horizontally and his friend drops a marble from the same height when the arrow is released. In the absence of air resistance, which of the following happens? The arrow hits the ground first. The marble hits the ground first. O Both hit the ground at the same time. You cannot tell from the information given.

Can you help me solve this?

During a recent winter storm, bales of hay had to be dropped from an airplane to a herd of cattle below. Assume the airplane flew horizontally at an altitude of 172 m with a constant velocity of 58.0 m/s and dropped one bale of hay every 4.0 seconds. It is reasonable to assume that air resistance will be negligible for this situation. About how far apart from each other will the bales land on the ground? Answer: m (rounded to the nearest whole number)

a boy kicks a football from the ground level with an initial velocity of 20 m/s at and angle of 30 degrees above the horizontal. What is the horizontal distance to the point where the football hits the ground if we neglect air resistance?

A cannon ball is fired at a wall that is 300 m away on level ground. The initial velocity of the cannon is 89 m/s, 40° above the horizontal. Don't assume the ball hits the wall at maximum height! What is the y-component of the ball's velocity when the ball hits the wall? h V; = 89 m/s 40° 300 m O 89.0 m/s O 9.81 m/s O 7.60 m/s O 18.2 m/s O 14.1 m/s O 2.99 m/s

Trying to escape his pursuers, a secret agent skis off a slope inclined at 30° below the horizontal at 53 km/h. To survive and land on the snow 100 m below, he must clear a gorge 53 m wide. Does he make it? Ignore air resistance. 30° m Vo 53 m (not to scale) 100 m Yes O No If so, by how much does the agent safely make the landing? If not, by how much does the agent miss the landing? (Enter the magnitude In meters.)

An eagle is flying horizontally at 7.6 m/s with a fish in its claws. It accidentally drops the fish. (a) How much time passes before the fish's speed doubles? (b) How much additional time would be required for the speed to double again?
