An ice cube slides from rest without friction down a long inclined ramp that makes an angle of 39.0 o with the horizontal. What is the speed of the cube after it slides 1.97 m down the plane?
Homework Answers
V^2 = U^2 + 2aS
a = gsin(theta)
=> V^2 = 0 + 2*9.8*sin(39)*1.97
=> V = sqrt (2*9.8*0.629*1.97) = 4.92 m/s after it slides 1.97 m down the plane

A car (initially at rest) slides down a smooth, 30 m long ramp (neglect friction on the ramp) that is inclined at 6 deg. from the horizontal. At the bottom of the ramp, this car hits a second, identical car that is also initially at rest on a horizontal road. The effective coefficient of friction for the cars on the road is 0.6. How far will the cars roll after the crash before stopping?
