GPE and KE

A 16-kg barbell is now 0.5 m above the floor. What is it's Gravitational Potential Energy in Joules?

The barbell weighs 160 N and the weighlifter lifted it 0.5 m. If W = Fd, how much work did the lifter do in Joules?

An engine applies a 250 N force to a car over 100 m. What is the work done by the engine in Joules?

If the engine does 25000 J of work, what is the Kinetic Energy of the car in Joules?

(hint, the car has a mass of 500 kg and is moving at 10 m/s² )

A book with a mass of 4.1 kg is raised a height of 2.3 meters above the ground. How much PE does the book gain in Joules?

Assume a 45 kg object has 1250 Joules of potential energy. What is its height above the ground in meters? (rounds to the hundredths)

What would be the kinetic energy of a 65 kg person who can run with a maximum speed of 13 m/s.

Answer in Joules, round to the tenths

What is the mass of a car that is moving at 25 m/s and possesses a total kinetic energy of 1,095,000 Joules?
