Question

A strong mass of of 50g is moving with a velocity are 20m/s, calculate its kinetic energy

Answer 1

hope you get answers

Answer 2

Answer:

The kinetic energy of a bullet of mass 50gram, moving with a velocity of 20m/s is 10J

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 $m=50g=0.0.05kg$

the velocity of the body $v=20m/s$

put the values in the above equation

we get the kinetic energy of the body $KE=\frac{1}{2}*0.05*20^{2}=10J$
