ENGINEERING MECHNAICS - DYNMAICS Homework # 4 1. The 25-lb block has an initial speed of vo = 10 ft/s when it is midway between springs A and B. After striking spring B, it rebounds and slides across the horizontal plane toward spring A, etc. If the coefficient of kinetic friction between the plane and the block is x = 0.4, determine the total distance traveled by the block before it comes to rest. 2 ft - ] ft k, = 10 Ib/in. ky = 60 Ib/in. i) = 10 ft/s | 2. The 10-Ib block is pressed against the spring so as to compress it 2 ft when it is at A. If the plane is smooth, determine the distance d, measured from the wall, to where the block strikes the ground. Neglect the size of the block. k= 100 Ib/its w - 4 ft 7 d
