A lowly high diver pushes off horizontally with a speed of 2.63 m/s from the edge of a platform that is 10.0 m above the surface of the water. (a) At what horizontal distance from the edge of the platform is the diver 0.834 s after pushing off? (b) At what vertical distance above the surface of the water is the diver just then? (c) At what horizontal distance from the edge of the platform does the diver strike the water?

In an article on the use of the sling as a weapon, the author states that a skilled slinger can sling a rock a distance of about 384 m. What is the minimum speed the rock must have when it leaves the sling to travel exactly 384 m? To solve this problem it will be necessary to first determine the required launch angle of the projectile. What launch angle must the projectile have in order to find the minimum speed required to achieve a given horizontal distance?

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 185 m with a constant velocity of 44.0 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?

A small rock is projected from the ground with the velocity with magnitude V0 and direction 53.1 degrees above the horizontal. A tall building is a horizontal distance of 26 m from where the rock was launched. The rock strikes the building 2 seconds after being launched. Neglect air resistance and assume the ground is level. At what vertical height above the ground does the rock the building?

A boy throws a tennis ball to the wall which is 7.5 m away. At the moment when the ball hits the wall, its vertical component remains unchanged while the horizontal component reverses. Assuming that the initial velocity of the ball is vo = 20.0 m/s, it makes an angle a = 60° with the horizon, and the release height is 1.5 m, find the vo = 20 m/s m. following (take the gravitational acceleration 9.8): a || a) At which height the ball hit the wall? 1.5 m b) How long did it take to reach the wall? c) How long was the ball in the air after it hit the wall? d) Where did the ball hit the ground? (distance from the wall) e) What is the velocity of the ball when it reaches the ground? f) What is the maximum height the ball reaches? 7.5 m Important: Draw a sketch defining a coordinate system: x- and y-axes and the origin. Without this sketch the problem will be considered as not-solved!

When throwing a ball, your hand releases it at a height of 1.5 m above the ground with velocity 6.8 m/s in direction 57° above the horizontal. (a) How high above the ground (not your hand) does the ball go?(b) At the highest point, how far is the ball horizontally from the point of release?

A stone is thrown from the top of a building upward at an angle of 60.0* to the horizontal and with an initial speed of 24.0 m/s. If the height of the building is 45.0 m. (a) how long is it before the stone hits the ground?(b) What is the speed of the stone just before it strikes the ground?(c) Where ?does the stone strike the ground

A lacrosse player is practicing against a wall. The ball leaves his stick 2.3 meters above the ground at a 33.5 degree angle from the horizontal with a speed of 9.3 m/s. The ball then hits the wall, 3.7 meters away. How high above the ground does the ball make contact with the wall?

A criminal is escaping across a rooftop and runs off the roof horizontally at a speed of 5 m/s, hoping to land on the roof of an adjacent building. Air resistance is negligible. The horizontal distance between the two buildings is D, and the roof of the adjacent building is 3.0 m below the jumping-off point. Find the maximum value for D.

A baseball is thrown with an initial speed of 37.5 m/s at a 42.0° angle in the absence of air resistance. a) What is the maximum height reached by the baseball? b) What is the magnitude and direction of the baseball's velocity at t = 2.50 s? c) What is the ball's height when it has traveled a horizontal distance of 55.0 m?
