The height of the roller coaster car is: h = 7.8 m
Step-by-step explanation:
Given
Mass m = 600 kg
Potential Energy P.E = 46,000J
To determine
Height h = ?
Using the formula
P.E = mgh
Here:
m is the massg is the gravitational acceleration (9.8 m/s²)h is the heightso substituting m = 600 kg, P.E = 46,000J, and g = 9.8
P.E = mgh
46000 = 600 × 9.8 × h
h = 46000 / 5880
h = 7.8 m
Therefore, the height of the roller coaster car is: h = 7.8 m
