Answer 2

Answer:

If a body of mass 5kg is moving along a straight line with a velocity of 10m/s and acceleration of 20m/ss is 250J

Explanation:

The kinetic energy of an object with mass (m) moving with velocity (v) is given by the formula

$KE=\frac{1}{2}mv^{2}$

From the given question, we have

mass of the moving body $m=5kg$

the velocity of the body $v=10m/s$

put the values in the above equation

we get the kinetic energy of the body $KE=\frac{1}{2}*5*10^{2}=250J$
