start with conservation of energy.
massbullet*velocitybullet=massgun*Vgun
vgun= .010*100 /1kg= ....
Now, ratio of KE
kebullet= 1/2 m v^2= 1/2 (.01)(100^2)
kegun= 1/2 *1*Vbun^2
massbullet*velocitybullet=massgun*Vgun
vgun= .010*100 /1kg= ....
Now, ratio of KE
kebullet= 1/2 m v^2= 1/2 (.01)(100^2)
kegun= 1/2 *1*Vbun^2
