A machine gun bullet of mass m leaves the barel at a speed of 100 `ms^(-1)` and has a kinetic energy of 1000 J. what is the mass of bullet ?

Text Solution

AI Generated Solution

To find the mass of the bullet, we can use the formula for kinetic energy (KE): 1. **Write down the formula for kinetic energy**: \[ KE = \frac{1}{2} mv^2 \] where \( KE \) is the kinetic energy, \( m \) is the mass, and \( v \) is the velocity. ...
