Question

A bullet of mass 50 gm is moving with the velocity of 720 km/hr. Calculate the kinetic energy of the bulet​

Answer 1

K = 5706.6 J

Step-by-step explanation:

Given that,

The mass of a bullet, m = 50 g = 0.05 kg

The velocity of the bullet, v = 720 km/hr = 477.77 m/s

We need to find the kinetic energy of the bullet​. The kinetic energy of an object is due to its motion. It can be given by the formula as follows :

`K=(1)/(2)mv^2\\\\=(1)/(2)* 0.05* 477.77 ^2\\\\K=5706.6\ J`

So, the required kinetic energy of the bullet is equal to 5706.6 J.
