Question

what will be the acceleration of a body of mass 400 gram when a force of 4 Newton acts on it ? what will be its velocity after 5 second if it starts from rest​

Answer 1

Answer:10m/s-2

Explanation:f=m*a

4=0.4*a

A=10

Initial velocity =0

V-0/5=10

V=50 m/s

Answer 2

Answer:

(i)10 m/s (ii)50 m/s

Explanation:

Mass of the body=400g=0.4kg

Force=4N

F=ma

or a=F/m

or a=4/0.4 m/s

or a=10m/s

v=u+at

=0+(10*5)m/s

=50m/s

This is your solution
