UNIT 2 Dynamics | 2.J Modified Atwood Machines NAME DATE X20XE Scenario in the diagram shown to the right a block of mass M has taken a quick hit from a bat. After the strike, its front end is at position x = 0 at time t = 0 and it is moving to the right with initial speed vo. The block slides on a rough surface and is also connected to a hanging mass object of mass m by a string that passes over an ideal pulley. The front end of the block reaches position x = D at time t=ti, the instant that the block comes to rest. The block then returns to position x = 0 at time t = 12, having a leftward speed v2 at that time. Using Representations The dots below represent the block on the table during the interval 0
