A hockey puck (mass = 4 kg) leaves the players stick with a speed of 12 m/s and slides on the ice before coming to rest. The coefficient of friction between the puck and the ice is 0.3. How far will the puck slide after leaving the players stick?

When the red kangaroo of Australia is moving at full speed, it can bounce at a speed of 8.5 meters per second, at an angle of 45 degrees above horizontal. Assuming the kangaroo is bouncing on level ground, what is the kangaroo’s hang time in the air during a single bounce?

a cannon shoots an artillery shell with an velocity of 400 meter/second at an indirect fire angle of 60 degrees. where does it land if friction effects and windage are neglected?

The average thrust created by the first stage engine of a model rocket is 50N. The rocket has an average weight of 10N with a burn time of 2 seconds. The rocket is initially fired vertically upward. When the rocket reaches maximum height, a second engine is fired creating a horizontal velocity (only) of 50m/s. Where does the rocket land relative to its launch point? Assume it was launched on a horizontal plain.

A basketball player jumps straight up for a ball. To do this, he lowers his body 0.270 m and then accelerates through this distance by forcefully straightening his legs. This player leaves the floor with a vertical velocity sufficient to carry him 0.940 m above the floor.

Grains from a hopper falls at a rate of 10 kg/s vertically onto a conveyor belt that is moving horizontally at a constant speed of 2 m/s. (a) What force is needed to keep the conveyor belt moving at the constant velocity?

You aim a rifle horizontally in a perfectly flat field while your friend holds a bullet at the same height as your rifle. You fire the rifle and your friend simply opens her hand simultaneously, allowing the bullet to drop. Your friend claims that both bullets hit the ground at the same moment. Do you agree? Justify your answer. Ignore air resistance.

A baseball player throws a baseball upward with an initial velocity of 40ft/sec and plans to catch it with a baseball glove. When will the ball strike the glove? assume the glove position in the same levation then the ball left his hand.
