Unformatted text preview: like a spring with a force constant of 400 N/m. Determine: a) The speed of the skier as he hits the snow bank. b) The amount he compresses the snow before coming to rest. Note: you can ignore energy lost due to friction while in the snow bank. (30 pts) 4. A large truck with a mass of 3200 kg is traveling at a speed of 75.0 km/h southbound. It crashes into a VW beatle with a mass of 1000 kg that was only traveling at a speed of 25.0 km/h southbound. The collision is totally inelastic. Determine: a) The final speed of the truck and car. (km/h) b) Is the kinetic energy conserved? 5. 2.00 kg ball A with a speed of 4.00 m/s has an elastic collision with 2.00 kg ball B with an initial speed of 3.00 m/s traveling in the same direction. What is the final speed of ball A and ball B. (m/s) (10 pts)...
