        A particle of mass m is moving with a uniform velocity v₁. It is given an impulse such that its velocity becomes v₂. The impulse is (equal to

        (a)    m [|v₂| = |v₁|

(b)    m[v₂²- v=₁²]

        (c)    m[v₁ + v₂]

        (d)    [v₂ – v₁]

Question

A particle of mass m is moving with a uniform velocity v₁. It is given an impulse such that its velocity becomes v₂. The impulse is (equal to

(a) m [|v₂| = |v₁|

(b) m[v₂²- v=₁²]

(c) m[v₁ + v₂]

(d) [v₂ – v₁]

Hrishant Goswami · Answer

(d) Impulse = final momentum - initial momentum = m(v 2 -v 1 )

A particle of mass m is moving with a uniform velocity v 1 . It is given an impulse such that its velocity becomes v 2 . The impulse is (equal to (a) m [|v 2 | = |v 1 | (b) m[v 2 2 - v= 1 2 ] (c) m[v 1 + v 2 ] (d) [v 2 – v 1 ]
