Potential and Kinetic Energy Answers

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

This diagram shows a skier moving down a hill.

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

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: )

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

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?

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?

The table shows information about four objects resting at the top of a hill. Which object is on the tallest hill?

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)
