1)when a person stands on bathroom scales the scale reads 60 kg. Suppose the person stands on the same scales when in an elevator (lift).

2)When a golfer strikes a golf ball it is in contact with the club head for about 1 ms and the ball leaves the club head with a speed of about 70m/s. If the mass of the ball is 50 g estimate the maximum accelerating force exerted on the golf ball, stating any assumptions that you make.
