WebSo the work done by the force of gravity in accelerating the mass over the first two seconds is force x distance = 10 newtons x 20 meters = 200 joules. So we find that the kinetic energy of a one kilogram mass moving at 10 meters per second is 50 joules, moving at 20 meters per second it’s 200 joules. Web900 joules b. 450 joules c. 3550 joules d. 2970 joules Solution: The potential energy of an object is PE = mgh where: PE = potential energy m = mass g = acceleration due to gravity g = 9.81 m/s² ≈ 10 m/s² h = height Listing the values m = 30 kg h = 3 m Solving for PE PE = mgh PE = (30 kg) (10 m/s²) (3 m) PE = 900 J Answer: A. 900 joules
