The kinetic frictional force will act during the time object is travelling on grass. Given , the co-efficient of kinetic friction, ηk = 0.3 The normal reaction from the ground will be, N = mg = 75(10) = 750Newtons So, the kinetic friction force is, f = ηkN = 0.3(750) = 225N Given the displacement is ∆x = 10m So, the work done by frictional force is, W = -f∆x = -225(10) Here, negative sign indicates that work done by friction is against the motion. or, W = -2250J
