In Figure (a), a 1.5 N force is applied to a 4.5 kg block at a downward angle 0 = 40 as the block moves rightward through 1.0 m across a frictionless floor. Find the speed vyof the block at the end of that distance if the block's initial velocity is (a) 0 and (b) 1.1 m/s to the right. (c) The situation in Figure (b) is similar in that the block is initially moving at 1.1 m/s to the right, but now the 1.5 N force is directed downward to the left. Find the speed vy of the block at the end of the 1.0 m distance. (a) (b) (a) Number i ! Units (b) Number i Units (c) Number Units
