Question

a body of mass 5 kg is moving with a velocity of 20 metre per second a force is applied on the body for 25 seconds and its attains a velocity of 40 metres per second what is the force applied​

Answer 1

Answer. therefore the total force applied on the body is 4 N .

Answer 2

Explanation:

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
