An object of mass 100 kg is initially at rest on a horizontal frictionless surface. at timet-0, a horizontal force of 10 n is applied to the object for 1 s and then removed. which of the following is true of the object at time t = 2 s if it is still on the surface? (a) it is at the same position it had at t 0, since a force of 10 n is not large enough to move such a massive object. (b) it is moving with constant nonzero acceleration. (c) it is moving with decreasing acceleration. (d) it is moving at a constant speed (e) it has come to rest some distance away from the position it had att 0.
