Question

an object of mass 5kg moving with a Speed of 5m/s is acted upon by force such that it's speed increases to 10m/s . calculate change in momentum in kg m/s​

Answer 1

3.75 N

Apply equation of kinematic

v=u+at

Acceleration, a=

t

v−u

=

20

25−10

=0.75ms

−2

Force= mass x acceleration

F=5×0.75=3.75N

Hence, force is 3.75N
