Question

A bullet of mass 50 g leaves the barrel of a gun with a velocity of 100ms-1

If all the chemical energy of the gun powder is converted into kinetic

energy of the bullet, what is the magnitude of the chemical energy.​

Answer 1

Explanation:

Find the mass

initial velocity

and final velocity

of the bullet from the given information. Find how much time is taken by the bullet to acquire final velocity from given data. <br> According to Newton's third law, is the recoil force experienced by the gun equal to the force by which the bullet leaves the gun? <br> Then, the force of the bullet,

<br> This 'F' value is equal to the recoil force on the gun. Find the value of 'F' by proper substitution of the values.
