A 106-kg object is initially moving in a straight line with a speed of 51. 3 m/s. (a) If it is brought to a stop with a deceleration of 1.97 m/s 2 , what force is required, what distance does the object travel, and how much work is done by the force? (b) Answer the same questions if the object’s deceleration is 4.82 m/s 2 .

```							W = Fs = (511 N) (273 m) = (1.40×105 N.m) (1 J/1 N.m) = 1.40×105 JFrom the above observation we conclude that, the work W is done by the force would be 1.40×105 J.
