Chapter 15, Problem 25P

(a)

To determine

The kinetic energy of a meteorite having a mass of $1.2\times {10}^{16}\text{ kg}$ which collides with the Earth at a velocity of $11\text{ km/s}$ before the collision.

(b)

To determine

The increase in temperature of a meteorite having specific heat capacity of $900\text{ J}\cdot {\text{kg}}^{-1}\cdot °{\text{C}}^{-1}$ when the thermal energy transferred to the meteorite is $20\%$ of the total kinetic energy before the collision.
