Unformatted text preview: stationary 1.4 Kg block, and the block starts to slide with the putty stuck on it after the collision. If the normal force acting on the block/putty from the track is 20 N at point B , find the initial speed of the putty. = _______ 51.3 m/s __________ 3. The frictionless track is made of a vertical section of length 0.8 R , a quartercircle with radius R , and a horizontal piece as shown. Released from rest at the top of the track (point A ), the smaller block 1 ( m 1 = M ) slides down and makes an elastic collision with the stationary larger block 2 ( m 2 = 4 M ) at the bottom of the track (point B ). As the smaller block slides back up along the track after the collision, it reaches the highest point C. Find the angle that locates point C on the track. 30 k 5 m 2 m k O R A B 1 2 0.8 R C = _______ 69.4 __________...
