While driving down a hill of constant slope θ = 5 ° in a 1600 kg car at a speed of 25 m/s, you slam on the brakes such that the wheels immediately lock up and the car is sliding on the pavement. The coefficient of friction, μ k , between the tires and pavement is 0.70. How far does the car skid before coming to a stop? θ = 5 ο PHYS2014/Fall 2010/Sample Final Exam Name:___________________________ OSU Physics Dept./Benton Recitation TA and Time:_________________ 2 2. Aliens from the planet Splorg have established an orbital base above the Earth from which to launch missions to create crop circles, tip cows, and abduct humans for medical examinations. The CIA, working in close collaboration with scientists from NASA, have estimated that the distance of the Splorigian base in its circular orbit is 7.66 × 10 8 m from the center of the Earth and that the mass of the Splorigian base is 38,000 kg. a) What is the orbital period of the Splorigian base? b) What is the kinetic energy of the Splorigian base in this orbit?

A cue ball (mass = 0.17 kg) moving at 3.0 m/s collides elastically head-on with a standard billiard ball (mass = 0.16 kg) that is initially at rest. Find the final velocities of both the cue ball and the billiard ball after the collision. 3.0 m/s PHYS2014/Fall 2010/Sample Final Exam Name:___________________________ OSU Physics Dept./Benton Recitation TA and Time:_________________ 4 4.
