Question

An object has a potential energy of 19,000 J at a height of 2.75 m. What is the objects mass?

Answer 1

m = 705 kg

Step-by-step explanation:

PE = m * g * h

m = PE / (g * h)

m = 19,000 (J) kg m/s² / (9.8 m/s² * 2.75 m)

m = 19,000 / (9.8 * 2.75 )

m = 19000 / 26.95

m = 705.009276438 kg
