A system consisting of two particles is known to have zero total momentum. Does it follow that
the kinetic energy of the system is zero as well? Explain.

Abox is pushed down at an angle of 32 degrees on a rough surface. the box moves to the right. what equation should be used to find the net force in the y-direction? answers: a. fnet, y = fn - fgb. fnet, y= fp - ffc. fnet, y = fn-fg- fpcos(32)d. fnet, y = fn-fg-fpsin(32)
