A body of mass 5kg moving with a velocity of 30ms‾¹ due east is suddenly hit by another body and changes its velocity to 50ms‾¹ in the same direction. Calculate the magnitude of the impulse received.

A. 100Ns
B. 150Ns
C. 250Ns
D. 400Ns

Correct Answer: Option A

A. 100Ns

Explanation

I = Ft = m(v – u)

= 5(50 – 30) = 100
