Suppose a cannon, placed on a moving cart with negligible friction in the wheel bearings, projects a cannonball straight up in the air. Does the speed of the cart have any effect on the height the ball attains or the time the ball is in the air?
From approximately what floor of a building must a car be droppedfrom an at-rest position so that it reaches a speed of 80.7 ft/sec whenit hits the ground? Each floor is 12ft higher than the one below it.
The juggling skateboarder is back outside He starts with a speed of of 3.0 m/s at a height ten meters above lake level, and then rolls down. Assuming that the effects of friction were negligible, how fast should he be moving when he is just two meters above lake level?
Small steel balls fall from rest through the opening at A at the steady rate of 3 per second. Find the vertical separation h of two consecutive balls when the lower one has dropped 1.6 meters. Neglect air resistance.
Suppose I need to toss an object of mass 5.2 up onto a shelf 5.94 meters above where my hands can reach. What is the minimum speed of toss necessary to do this? Your answer should be in meters per second, but don't write teh unit, just the number. You can approximate the acceleration due to gravity at the earth's surface as 10 meters per square second.

A softball having a mass of 0.25 kg is pitched horizontally at 120 km/h By the time it reaches the plate, it may have slowed by 10%. Neglecting gravity, estimate the average force of air resistance during a pitch. The distance between the plate and the pitcher is about 15 m.
Find the net work done by friction on the body of a snake slithering in a complete circle of radius 1 m. The coefficient of friction between the ground and the snake is 0.25, and the snake's weight is 54.0N.
Use the conservation of energy todetermine the minimum vertical speed that anobject must have at the surface of the earth sothat its speed at infinity would be zero. Thisspeed is known as the escape speed of theearth. For this problem, you should assume thatthe gravitational interaction with the earth isthe only interaction which the object feels.
