Question

If a net force of 7 N was constantly applied on 400 g object at rest, how long will it take to raise its velocity to 80 m/s? Also find how much distance will it cover during that time?

Answer 1

Answer:

We can first find the acceleration as we know the force and mass

Also we know u=0 and v= 80m/s

So, by applying eq of motion

V = u + at

We can find "t" which will come out to be 4.5 s
