Question

An object of mass 5 kg is moving with a velocity of 10 ms". A force is applied so that in
15 s, it attains a velocity of 25 ms"!. What is the force applied on the object?​

Answer 1

Answer:

answer :

Force=mass × acceleration

acceleration=(change in velocity) / time interval

Initial velocity=10m/s

Final velocity=25m/s

Time interval=20s

Therefore, acceleration=(25 - 10)/20

=0.75m/s2

Force=mass x acceleration

=5x0.75

=3.75N

so the force applied on the object is 3.7N
