A floating ice block is pushed through a displacement?

A floating ice block is pushed through a displacement d = (24 m)i - (12 m)j along a straight embankment by rushing water, which exerts a force F = (150 N)i - (175 N)j on the block. (a) How much work does the force do on the block during the displacement?J(b) Does the ice block speed up?move at constant speed?slow down? (b) What is the angle between the force and the displacement?°

a. W = F d where the x and y are considered separatelyx dir: W = 24 * 150 = 3600 Joulesy dir: W = -12 * -175 = 2100 Joulestotal work = 3600 + 2100 = 5700 Joulesb. speeds upc. the force vector and the displacement vector are in the same direction. Thus, the angle between F and d is 0 degrees... Show More
