Question

A body of mass 4 kg initially at rest is subjected to a force 16N .what is the K.E accquired by the body at the end of 10 s ?​

Answer 1

@hey mate !!

here is your answer:-

m=4kg, F=16N, t=10sec

a=F/m

=16/4

=4m/s^2

v=u+at

=0+4×10

=40m/s

The K.E of energy accquired by the body:----

K=1/2mv^2

= 1/2×4×(40)^2

= 3200J

Thanks ❤

hope it's help you ✔✔

Answer 2

Answer:

F=ma

a=F/m

=16/4

a=4

V=u + at

V=0 + 4×10

V=40

K.E.=1/2mv^2

=1/2×4×40×40

=3200
