A force of 200N pulls a sledge of mass 50kg and over comes a constant frictional force of 40N. What is the acceleration of the sledge ? ( laws of motion )

Since the block movies at constant velocity, it's acceleration is zero. Hence, according to Newton's second law of motion , net force =0 ( since net force = Mass * acceleration )
Let force applied be F (N), frictional force be f (N).
Frictional force is always opposes the net force applied, hence Net force on block = F - f =0
Thus, F = f
100 = f
Thus, frictional force = 100 N
