Question
A medium-sized apple provides about 95.0 Calories of energy.
HINT
(a)
Convert 95.0 Cal to joules.
 J
(b)
Suppose that amount of energy is transformed into kinetic energy of a 1.53 kg object initially at rest. Calculate the final speed of the object (in m/s).
 m/s
(c)
If that same amount of energy is added to 3.79 kg (about 1 gal) of water at 17.7°C, what is the water's final temperature (in °C)? The specific heat of water is 
c = 4186 
J
(kg · °C)
