A block of mass 2kg is sliding on a smooth surface. At t=0, its speed is v_(0)=2m//s . At t=0, a time varying force starts acting on the block in the direction opposite to v_(0) if the speed of object is (38)/(N)m//s at t=10s. Find the value of N

A force of 75 N is applied to a block of mass 25 kg, resting on a smooth horizontal surface. In how much time, the block will acquire a speed of 12 m/s?
