A snowball rolls down a 200 m long hill at an angle of 30o above the horizon. After leaving the hill it rolls toward a 1200 kg small car on an icy horizontal surface. The snowball has a mass of 200 kg and a diameter of 1.2 m.
(a) What is the speed of the snowball at the bottom of the hill?
(b) The snowball collides with the car and all the snow covers the car. What is the speed of the snow covered car after the collision?
(c) What fraction of the snowball's kinetic energy remains after the collision? Answer: 0.143
(d) If the snow covered car slides off a 100 m high cliff, how far from the edge of the cliff does the car land?
Protons are projected with an initial velocity v0 = 10360 m/s into a region where a uniform electric field E = 670 N/C is present. The protons are to hit a target that lies a horizontal distance of 1.27 mm from the point where protons are launched..
