Question

The figure shows the position-time
x t   graph of one dimensional motion
of a body of mass 0.4 kg. The
magnitude of each impulse is
1) 0.4 Ns 2) 0.8 Ns
3) 1.6 Ns 4) 0.2 Ns

Answer 1

Answer:

Step-by-step explanation:

In each impulse, x varies from 0 to 2m and again from 2 m to 0 during the time

interval of 4s. We have,

Impulse = Change in momentum

m(v2 - v1 ) = 0.4 x 2 = 0.8 Ns
