Q. A toy car moves at a velocity of 65.00 m/s on a compass heading of 115degrees. What are the components, magnitude and direction of car?

Q. A solid sphere is thrown on a horizontal plane in such a way that at first it slips without rolling in a direction parallel to the plane with velocity v0=34 m/s. If the coefficient of kinetic friction of the surface of the plane is 0.36, at which time the motion of the sphere becomes a pure rolling?
