Question

Numerical
A constant force is acting on a body of mass 3 kg changes its speed
from 2 m/s to 3.5 m/s in 15 second what is the magnitude of the force​

Answer 1

Answer:

F=0.3N

Explanation:

u=2m/s,. v=3.5m/s t=15sec. a=?

by using newton equation v=u+at

3.5=2+(a×15)

a=0.1m/s^2

so Magnitude of force F=ma

=3×0.1=0.3N
