Title
A spinning sphere has a moment of inertia of 12 kg.m^2 and has an angular momentum of 18 kg.m^2/s. What is the angular speed of the sphere?
Two 500-g carts move on a frictionless air track. Cart A is moving at +0.1 m/s when it collides into Cart Bat rest. The two carts get stuck together. At what velocity will the combined carts move?
A 10-kg box is sliding across an ice rink at 10 m/s. A skater exerts a constant force of 10 N against it. How long will it take for the box to come to a complete stop?
A force of 2.0 N exerted on an object for 100 milliseconds increases the objects velocity by 1.0 m/s. What was the mass of the object?
A 0.5-kg object has a momentum of 10 kg.m/s. What is its speed?
A 10-N force is applied to a hockey puck over a period of 0.1 s. What is the change in momentum of the hockey puck?
A 3 ton Toyota land cruiser travelled at a speed of 45m/s, collides with a 2 ton comfort taxi which was parked in front of the traffic lights intersection. After the collision, both cars lock together and move off in one direction. Determine a) the speed
A 1000-kg car moving at a constant velocity of + 11.0 m/s strikes a concrete barrier and comes to a complete stop in 2.0 s. What is the average force acting on the car?
A rifle fires a 4.0-g bullet at a velocity of 950 m/s. If the bullet is in the rifle barrel for only 0.1 s, what average force does the rifle exert on the bullet?
Measurements and calculations from a slow motion video show a 50.0-g ball hitting the ground at +5.0 m/s and bouncing back up at -4.0 m/s. By how much did the balls momentum change?
