Q.12 A block has 10 kg mass. A strong wind force of magnitude equal to half the weight of the block is acting towards east. At a certain moment, velocity of the block is u m/s towards east and it is at point P. At that moment, another force towards west started acting on the block. Magnitude of that force is 1.3 times the weight of the block. The block came to a halt at point which is 4 m away from point P. Calculate u and write that as your answer. Q.12 A block has 10 kg mass.
