Question

velocity time graph of A ball of mass 50 gram rolling on a floor is given the frictional force of the floor on the wall will be-

Answer 1

The acceleration is given by slope of v−t graph acceleration=−808    
                                                                                                = -10 ms−2
mass of ball  = 50 g = 0.05 kg

Force due to friction = mass  × retardation
                                = 10×0.05 =0.5N
