Question

A 4.70g lead bullet traveling at 600 m/s is stopped by a large tree. If half the kinetic energy of the bullet is transformed into internal energy and remains with the bullet while the other half is transmitted to the tree, what is the increase in temperature of the bullet?
Answer in degree Celsius

Explanation / Answer

here,

specific heat of lead , C = 128 J/kg

mass of bullet , m = 0.0047 kg

speed , u = 600 m/s

the kinetic energy converted into heat energy for lead , E = 0.5 * KE

let the change in temprature of bullet be dT

0.5 * KE = heat gained by bullet

0.5 * 0.5 * m * u^2 = m * C * dT

0.5 * 0.5 * 600^2 = 128 * dT

dT = 703.13 degree C

the increase in temprature of bullet is 703.15 degree
