Question

A constant force acts on an object of mass 5 kg for a duration of 2 second it increases the objects velocity from 3 minute per second into 7 minute per second find the magnitude of the applied force

Answer 1

given, mass=5kg
initial velocity=3m/s
final velocity=7m/s
acceleration=?

a=final-initial velocity/time
7-3=4m/s/2s=2m/s
magnitude of force =mass×acceleration
5×2
=10N
