The mine car is being pulled up to the inclined plane using the motor M and the rope-and-pulley arragement shown. Determine the speed vp at which a point P on the cable must be traveling toward the motor to move the the car up the plane with a constant speed of v = 5 m/s.

[A]. VP = 1.667 m/s
[B]. VP = 2.50 m/s
[C]. VP = 15.00 m/s
[D]. VP = 10.00 m/s

Answer: Option C

2Sc +(Sc - Sp) = l

3Sc - vp = 0;
vp = 3*(-5) = -15m/s = 15m/s
