A body of mass 50kg is dragged along a horizontal rough surface at a uniform speed of 3m/s. If the dragging from is 15N, find the force resisting the motion of the body
1 answer
The force resisting the motion of the body is 75N. This is calculated by using the equation F = ma, where F is the force, m is the mass, and a is the acceleration. In this case, the acceleration is 0, since the body is moving at a uniform speed. Therefore, F = ma = (50kg)(0) = 0. Since the force of the dragging force is 15N, the force resisting the motion of the body is 15N + 0 = 75N.
