(a) Rotating setup and (b) stationary setup. (a) Draw a free-body diagram for mass M, while in motion (Fig. 5.1a). Identify the centripetal force. Assume the mass hangs vertically. 7 Chapter 5. Prelab Exercises for Angular Motion (b) If the mass of M₁ = 525 g, what is the magnitude of the tension force in the cord while in motion? (Hint: refer to your free body diagram in (a) and Fig. 5.1a.) (c) Calculate the magnitude of the force exerted by the spring on mass M₁ = 525 g, moving in a circle of radius r = 21 cm, as shown in Fig. 5.1(a). The mass makes 19 revolutions in 17 seconds. (d) Determine the mass m, suspended over the pulley shown in Fig. 5.1(b), which stretches the spring by the same amount as during the rotation in (c).

Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

An electric hot water heater consumes 3.1 kilowatts of electricity and converts it to heat. How long will it take the water heater to heat a 67 gallon tank of water from 10 degrees Celsius to 50 degrees Celsius? (1 kilogram of water is 0.37 gallons, 1 Calorie = 4200 J). It may be helpful to refer back to the weekly handout for guidance on this problem. Your final answer should be in minutes (rounded to the nearest 10 minutes).
