A 75 kg man running at 2.5 m/s jumps off a roof that is 3 m high. As he hits the ground, he tucks into a ball and rolls without slipping to break his fall. Modeling the man as a solid sphere of a radius 0.75 m, assuming no rotational motion before he hits the ground, and ignoring any effects of him tucking into a ball, what is his center of mass velocity on the ground?
When Brian, whose mass is 66 kg, jumps from the roof of his house onto a...
When Brian, whose mass is 66 kg, jumps from the roof of his house onto a trampoline 3.2 m below, the trampoline sags 22 cm at its maximum deformation. (a) How much energy is lost to heat and sound in the trampoline if Brian bounces back only 1.0 m above the level of the trampoline?
Erica kicks a soccer ball 12 m/s at horizontally from the edge of the roof of a building which is 30.0 m high
Erica kicks a soccer ball 12 m/s at horizontally from the edge of the roof of a building which is 30.0 m high. a. When does it strike the ground? b. With what velocity does the ball strike the ground?

a) A man jumps off the roof of an office building onto a trampoline 30 m below. His speed is 5 m/s when he umps from the roof and his mass (with all of her gear) is 60 kg. How high will he go when he bounces back up from the trampoline? You can assume his speed at the top of his bounce is zero. b) Describe the changes in mechanical energy that take place during his jump. c) A...

A basketball player is running at 4.3 m/s toward the basket when he jumps into the air to dunk the ball. he maintains the same horizontal velocity while in the air. What vertical velocity does he need to rise 0.750 m above the floor in m/s? And at what horizontal distance from the basket, in meters, must he start his jump to reach his maximum height at the same time as he reaches the basket in m?

A baseball player is running at 4.45 m/s toward the basket when he jumps into the air to dunk the ball. He maintains the same horizontal velocity while in the air. (a) What vertical velocity does he need to rise 0.750 m above the floor in m/s? Nu_0y = At what horizontal distance from the basket, in meters, must he start his jump to reach his maximum height at the same time as he reaches the basket in m?
A solid cylinder of radius 10 cm and mass 13 kg starts from rest and rolls without slipping a distance of 6.0 m down a house roof that is inclined at 30°
A solid cylinder of radius 10 cm and mass 13 kg starts from rest and rolls without slipping a distance of 6.0 m down a house roof that is inclined at 30°. (See the figure.) What is the angular speed of the cylinder about its center as it leaves the house roof? The outside wall of the house is 5 m high. How far from the edge of the roof does the cylinder hit the level ground?
b. A girl, standing on the roof of a house which is 5.00 m high, throws a stone vertic upward. It strikes the ground 7.00 s after being thrown.
