A body of Mass 10kg is acted upon by a constant force of 30Ñ for 2sec.Calculate the kinet energy gained by the body.

Answer 1

Answer:

give

Explanation:

Given:-

m=10 kg

F=30N

t=2 sec

therfore, F=m×a

a=F/m

=30/10

=3 m/s^2

as we know,

a=v/t

v=a×t

=3×2

=6m/s

.•.K.E=1/2mv^2

=1/2×10×(6)^2

=1/2×10×36
