1.	Consider two objects of masses 5 kg and 20 kg which are initially at rest. A force 100 N is applied on the two objects for 5 second. (a) What is the momentum gained by each object after 5 s? (b) What is the speed gained by each object after 5 s?
Answer» Solution :FINAL MOMENTUM on each object`Delta P = D Delta t=100 xx 5 =500 kg ms^(-1)` Final SPEED on the object of mass `5 kg = 500//5 =100 ms^(-1)` Final speed on the object of mass `20 kg = 500//20 =25 m s^(-1)`
