CE 222 ENGINEERING MECHANICS II ( FALL 2003 – 2004 ) EXERCISE SHEET IV ( http://www.ce.metu.edu.tr/~ce222 ) 1. When 5 kg block is 6 m away from the wall, it is sliding at V 1 = 14 m/s. If the coefficient of kinetic friction between the block and the horizontal plane is m k = 0.3, determine the impulse of the wall on the block necessary to stop the block. Neglect the friction impulse acting on the block during the collision. 2. Block A has a mass of 3 kg and B has a mass of 5 kg. If the system is released from rest, determine the velocity of each block in t = 4s. Neglect the mass of the pulleys. 3. The 10 kg block is held at rest on the smooth inclined plane by the stop block at A. If the 10 g bullet is traveling at 300 m/s when it becomes embedded in the 10 kg block, determine the distance the block will slide up along the plane before momentarily stops 4. The slider block B is confined to move within the smooth slot. It is connected to two springs, each of which has a stiffness of k = 30N/m. They are originally stretched 0.5 m when s = 0 as
