Question

a force applied to an object of mass 400g changes it's velocity from 3ms-1
to 4ms-1 in 10 s. calculate the magnitude of force​

Answer 1

Answer:

Explanation:

u=3m/s

v=4m/s

t=10 sec

mass=0.4kg

v=u+at

4=3+10a

10a=4-3

a=1/10m/s^2

a=0.1m/s^2

force=mass*accelertaion

force=0.4*0.1

force=0.04N

Answer 2

Answer:
