Flow speed of river is 2m/s. A stone is thrown from point O at time t=0 with a velocity V→=(v1jˆ+v2jˆ+20)kˆm/s. (a) Find v1, v2 such that the stone hits the block. (b) If the speed of throw is kept fixed, what is the maximum value of time t at which it is possible to throw the stone to bit the block.

0) at t=0. The particle A move on a circle given by X2+Y2=3600 and with a speed 6πm/s 0). (b) Calculate average acceleration of particle A during the motion. Two particles A and B are situated at point (60 while B moves with a constant velocity. (a) Find the velocity of B so that the collision takes places between A and B at point (60
