A block moving on a friction-less surface has an initial velocity of v m/s when a force F is applied on the block. The force varies with time t according to the graph shown in Fig. Q.2. If the block reaches a speed of 6.5 m/s at the instant when time t= 6 s, determine the initial velocity of the block. F [N] 40 t [s] 1.5 3.0 4.5 6.0 - 20 Figure Q.2
