Question

An impulse is supplied to a moving object with the force at an angle of 1200 with the velocity vector. The angle between the impulse vector and the change in momentum vector is
  1. 1200
  2. 00
  3. 600
  4. 2400

A
1200
B
00
C
600
D
2400
Solution
Verified by Toppr

Impulse of a force which is defined as force times its duration of action is equal to the change in the momentum of the body. Hence the direction of impulse will be along the direction of change in momentum.
