Collisions among objects are governed through laws of momentum and energy. While a collision occurs within an isolated system, the total momentum of the system of objects is conserved. Provided in which there no net external forces are acting upon the objects, the momentum of all objects before the collision equals the momentum of all objects after the collision. If there are only two objects included in the collision, after that the momentum lost through one object equals the momentum gained through the other object.
A 2350-kg granite tombstone absorbs 2.8 x 10 7 J of energy from the Sun to change its temperature from 5.0°C at night to 20.0°C during an autumn day. Verify the specific heat
