Question

a body of mass 1 kg moves with velocity 10 ICAP metre per second it is given an impulse such that the velocity becomes 10 j cap metre per second then magnitude of impulse is equal to​

Answer 1

Answer:

Correct option is D)

lets consider m= mass of a particle

v

1

= initial velocity

v

2

= final velocity

The impulse is vector quantity and is equal to change in momentum,

I=mv

2

−mv

1

I=m(v

2

−v

1

)

The correct option is D.
