A ball is thrown horizontally from the top of a building 74 m high. The ball strikes the ground at a point 90 m horizontally away from and below the point of release. What is the speed of the ball just before it strikes the ground? (note: speed is magnitude of velocity at that point).

You are going to throw a ball upward at an angle of 5.80 degrees. If you can throw it with an initial speed of 24.7 m/s, what is its initial vertical velocity component? Your Answer: Answer

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 ball is thrown from the top of a tower at an angle of 40o to the horizontal with an initial speed of 6.60 m/s.  During its flight, the only force acting on the ball is the force of gravity.  It takes 3.55 s until the ball hits the ground.  How tall is the tower?

A lowly high diver pushes off horizontally with a speed of 2.88 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 0.875 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?

A criminal is escaping across a rooftop and runs off the roof horizontally at a speed of 5.1m/s, hoping to land on the roof of an adjacent building. Air resistance is negligible. The e horizontal distance between the two buildings is D, and the roof of the adjacent building is 2.0m below the jumping-off point. Find the maximum value for D.

A fox fleeing from a hunter encounters a 0.770 m tall fence and attempts to jump it. The fox jumps with an initial velocity of 7.30 m/s at an angle of 45.0°, beginning the jump 1.93 m from the fence. By how much does the fox clear the fence? Treat the fox as a particle.

A 0.75 kg football is thrown from a height of 1.8 m and has an initial velocity of 16.0 m/s [R 34°U] (34° above the horizontal axis). Assuming that there is air resistance and that the ball lands on the ground, what is the distance the ball will travel horizontally?

As shown in the figure, a rock is shot upward from the edge of a vertical cliff. It leaves the edge of the cliff with an initial velocity of v directed at 30° from the horizontal direction and experiences no appreciable air resistance as it travels. The rock lands 2 seconds later. How high is the building?
