A medium-sized apple provides about 95.0 Calories of energy.
(a) Convert 95.0 Cal to joules.
(b) Suppose that amount of energy is transformed into kinetic energy of a 2.03 kg object initially at rest. Calculate the final speed of the object (in m/s).
(c) If that same amount of energy is added to 3.79 kg (about 1 gal) of water at 21.7°C, what is the water's final temperature (in °C)? The specific heat of water is
c = 4186
J
(kg · °C)
