Question

A body of mass og 4 kg initially at rest is subject to a force of 16n.What is the kinetic energy aquired by the body at the end of 10 secs

Answer 1

Answer:

3200 J

Explanation:

F=m*a

16=4*a

a=4 m/s^2

v=u+at

v=0+4*10=40 m/s

K E=0.5*m*(v)^2

    =0.5*4*(40)^2

    =3200 J

I hope this helps you.
