Plot the gravitational potential energy of a 2 kg ball as a function of height above the floor, presuming the potential energy is zero at the floor. If the ball has an initial velocity (at height h=0) of 12 m/s, plot both the total energy and the kinetic energy of the ball as a function of h. What is the maximum height attained by the ball?

Homework Answers

Answer #1

At maximum height, the total energy is the potential energy.

When the ball touches the floor, the total energy is kinetic energy

Equating the 2 equations, one obtains the maximum height attained by the ball

The total energy is

The plot of potential energy vs h is shown below

The plot of kinetic energy vs h and total energy E is shown below

A ball is attached to a vertical spring. The ball is initially supported at a height y so that the spring is neither stretched nor compressed. The ball is then released from rest and it falls to a height y - h before moving upward. Consider the following quantities: translational kinetic energy, gravitational potential energy, elastic potential energy. When the ball was at a height y - (h/2), which of the listed quantities has values other than zero joules? Please...

A 1-kg ball is released from a height of 6 m, and a 2-kg ball is released from a height of 3 m. Air resistance is negligible as they fall. Which of the following statements about these balls are correct? (There could be more than one correct choice.) Both balls will reach the ground with the same speed. As they reach the ground, the 1-kg ball will have more kinetic energy than the 2-kg ball because it was dropped from...

From this week's lab you learned that the change in gravitational potential energy of a falling body can be captured and stored as a rotational kinetic energy of a spinning disk. This gave you the idea of a regenerative driver for an elevator in a tall building. When an elevator goes down the corresponding change in the gravitational potential energy of the elevator is transformed into the rotational kinetic energy of a solid disk-shape flywheel which can be extracted and...
