1. Determine the specific heat of a certain metal if a 450-g sample of it loses 34,500 joules of heat as its temperature drops by 97degC.
2. The temperature of a 55-g sample of a certain metal drops by 113degC as it losses 3,500 J of heat. What is the specific heat of the metal?
3. A golfer wishes to hit his drives further by increasing the kinetic energy of the golf club when it strikes the ball. Which would have the greater effect on the energy transferred to the ball by the driver – doubling the mass of the club or doubling the speed of the club head? Explain.
4. A stone is dropped from a certain height and penetrates into the mud. All else being equal, if it is dropped from twice the height, how much farther should it penetrate?
