1. A 120 kg body initially at rest is acted upon by a constant force of 75 N for 7 sec. After which an opposite force of 55 N is applied. In what additional time in seconds will the body come to rest? 2. A 250 N block is in contact with a level plane whose coefficient of friction is 0.15. If the block is acted upon by a horizontal force of 60 N, what time will elapse before the block reaches a velocity of 10 m/s?
