Unformatted text preview: straight horizontal section and a quartercircle with radius R = 5 m. A 1 Kg lump of putty is thrown toward the stationary 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 98 N at point B , find the initial speed υ of the putty. A B R R υ Ans : 70 m/s O R A B 1 2 R C θ CHANG 4 The frictionless track is made of a vertical section of length 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 = 3 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 θ that locates point C on the track. Ans : 60 ˚...
