Two nonconservative forces are present: friction does -2.00 104 J of work on the car, and a chain mechanism does +3.00 104 J of work to help the car up a long climb. Illustrate what is the change in the car's kinetic energy, ΔKE = KEf - KE0, fro..
A spring of k=12.00 N/m has a block of mass 11- kg attached to it on a frictionless table. If the block is pulled a distance 0.17m to the right and released from rest, how long would it take the block to return to its equilibrium position? Give yo..
A 1000 kg aircraft going 25 m/s collides with a 1500 kg aircraft that is parked and they stick together after the collision and are going 10 m/s after the collision. If they skid for 5.4 seconds before stopping, how far did they skid?
The bullet becomes embedded in the block. If the bullet-block system compresses the spring by a highest of 90.0 cm, what was the speed of the bullet at impact with the block.
