1. a 16.0 g bullet is shot into a wooden block at rest with mass 4550 h on a frictionless surface. the block moves 1.20 m/s after the bullet strikes and becomes lodged in the block. find the speed of the bullet before striking the block.
2. One cart of mass 15.0 kg is moving 5.00 m/s to the right on frictionless track and collides with a cart of mass 3.00 kg. the final velocity of the carts that become stuck together after the collision is 1.50 m/s to the right. Find the velocity if the second cart before the collision
A car is traveling at 43.2km/hr on a flat, concrete highway. If the brakes are applied such that skidding occurs, the kinetic coefficient of friction between the road and tires is 0.808. If anti-lock brakes are properly applied after that no skidd..
