Question

A body of mass 10kg is acted upon by a constant force of 30N for 2sec. Calculate the KE gianed by the body

Answer 1

Answer:

180

Explanation:

ke=1/2mv^2 --1

f=ma--2

putting given values in 2

we get,

a=3

a=v/t

by above formula we get,

v=6

putting all values in one we get

we get ke=180

Answer 2

given,

mass--10kg

force--30N

Time--2 second

kinectic energy--?

now,

soln;

answer --180.

The kinectic energy gained by rhe body is 180.
