Basketball has a mass of 0.1kg m = 0.1 kg The basket ball is moving at constant speed, this shows that it is not accelerating. So, acceleration is zero a = 0m/s² The constant speed is 6m/s v = 6m/s So, force to keep it moving with this constant speed can be calculated using Newton second law of motion F = ma F = m × 0 F = 0N So, since the basket ball is moving at constant speed, then, the force need to keep the ball moving is 0N.
