How does momentum of a body change if its kinetic enerygy is doubled

Explanation:

Momentum is directly proportional to velocity. If momentum of an object is doubled , but itsmass does not increase (so velocity remains below the speed of light) then its velocity isdoubled. If the velocity is doubled, then the kinetic energy increases by four times.

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
