Question 2 (5 Marks) A smooth cube, of mass 50 g, slides with an initial velocity of 5 nits up a slope as shown in the diagram below. The ramp is 120 cm high; friction can be ignored. V=5mls / 1200111 / Ground level a) Sketch a free body diagram for the situation where the cube is moving up the slope. [2] b) How long does it take the cube to travel to the top of the slope given the angle 9 is 20\"? [2] The same cube is now travelling on a smooth horizontal surface with a velocity of 4 mfs. It then projected horizontally and hits the ground as shown in the diagram below. V=4mfs D- Ground level :1 How far from the bottom of the ramp does the smooth cube hit the ground level? [1]
