Question

A car with mass 1450 kg, is rolling along a flat road at 15 m/s.

It then starts to roll up a hill. How much height will it gain up
the hill? Assume the driver doesn't press any of the pedals.

Answer 1

11.5 m

Step-by-step explanation:

Kinetic energy = potential energy

½ mv² = mgh

½ v² = gh

h = v² / (2g)

h = (15 m/s)² / (2 × 9.8 m/s²)

h = 11.5 m
