1.	A body of mass 2 kg is free to move along x-axis. It is at rest at t = 0. From t = 0 onwards it is subjected to a timedependent force F(t) in x-direction. The variation of F with time is as shown :The change in momentum during journey is (in N-s) : (1) 4.50 (2) 7.50 (3) 5.06 (4) 14.06
Answer» Correct option (1) 4.50 Explanation: Change in momentum = impulse = area under F–t graph area = +1/2 x 4 x 3 -1/2 x 1.5 x 2 = 6-15 = 4.5.

Answer»

Correct option (1) 4.50

Explanation:

Change in momentum = impulse = area under F–t graph

area = +1/2 x 4 x 3 -1/2 x 1.5 x 2 = 6-15 = 4.5.
