The magnitude of a force as a function of time can be represented by F(t) = Rt - St + Z. The direction of the force does not change. If the force is exerted on an object of mass M, the change in velocity of the object between t = 0 and t = T seconds is A 2RT - S B 2RT S M M C RT3 - 1ST? + ZT D 1 RT 3 1 ST2 3 M + ZT 2 M M E RT 2 ST M M
