Potential and Kinetic Energy Answers

Olivia is on a swing at the playground.

A roller coaster with a potential energy of 235,200 J sits at the top of a 30 m high hill. What is the mass of the roller coaster? (Formula: PE = mgh)

This diagram shows a baseball’s motion.

The diagram shows a person holding a bow and arrow.

An object has a velocity of 8 m/s and a kinetic energy of 480 J. What is the mass of the object? (Formula: )

Which two factors are used to calculate the kinetic energy of an object?

A soccer ball is traveling at a velocity of 50 m/s. The kinetic energy of the ball is 500 J. What is the mass of the soccer ball? (Formula: )

What is the kinetic energy of a ball with a mass of 0.5 kg and a velocity of 10 m/s? (Formula:)

Ella has a mass of 56 kg, and Tyrone has a mass of 68 kg. Ella is standing at the top of a skateboard ramp that is 1.5 meters tall. Which conclusion is best supported by the given information?

Let's consider a scenario of a roller coaster ride. As the roller coaster at the top begins to descend, it loses height, which means its potential energy decreases and kinetic energy starts increasing and reaches its maximum value.By using the above scenario, which statement best compares potential and kinetic energy?
