Question

Q 14. A body of mass 1 kg has a
velocity of 50m/s . After 3 seconds
velocity becomes 65 m/s. The change
of momentum of the body is
*
O 1.5 kg metre/s
O 150 kg metre/ s
O 15 kg metre/s
O None of these​

Answer 1

Answer:

none of these

Explanation:

change in momentum dp/dt = mdv/dt

= 1 x (65 - 50)/ 3

= 15/3

= 5 kg m /s

may be like this:) hope uh got it, or I'm wrong than tell me:)
