Question

A student collect data about a toy motorized airplane.

Mass = 4 kg
Time = 3 sec
Height = 5 meters
Velocity = 2 m/sec
Gravity acceleration = 10 m/sec2

What is the potential energy?

Answer 1

PEg = 196.2 J

Explanation:

PEg = mass * gravitational field* height

PEg = 4kg * 9.81m/s² * 5m

PEg = 196.2 kg m²/s²
