a)
Interpretation: Whether sled in rest at hilltop or that slid down the hill has higher kinetic energy should be determined.
Concept introduction: Capacity to perform work is known as energy. Two basic types of energies are kinetic and potential energy.
Potential energy is that type of energy that arises due to relative position of objects with respect to other objects.
Kinetic energy comes into play when body possesses some kind of motion in it.
b)
Interpretation: Whether water above dam or that is fallen over dam has higher kinetic energy should be determined.
Concept introduction: Capacity to perform work is known as energy. Two basic types of energies are kinetic and potential energy.
Potential energy is that type of energy that arises due to relative position of objects with respect to other objects.
Kinetic energy comes into play when body possesses some kind of motion in it.

- As a child plays on a swing, at what point in her movement is her kinetic energy the greatest? At what point is potential energy at its maximum?arrow_forwardHow much heat is required to raise the temperature of 100. grams of water from 25C near room temperature to 100.C its boiling point? The specific heat of water is approximately 4.2Jperg-K. a.3.2104J b.32J c.4.2104J d.76Jarrow_forwardA 45-g aluminum spoon (specific heat 0.88 J/g C) at 24 C is placed in 180 mL (180 g) of coffee at 85 C and the temperature of the two become equal. (a) What is the final temperature when the two become equal? Assume that coffee has the same specific heat as water. (b) The first time a student solved this problem she got an answer of 88 C. Explain why this is clearly an incorrect answer.arrow_forward
