Question

A car is rolling down a hill and has 23 J of kinetic energy. It is rolling 15 m/s. What is the mass of the car?

Answer 1

[AI-generated answer — Bot GPT 3.5]

To find the mass of the car, we can use the formula for kinetic energy:

KE = (1/2) * m * v^2

Where:
KE = kinetic energy (23 J)
m = mass of the car
v = velocity of the car (15 m/s)

Plugging in the values:

23 = (1/2) * m * (15)^2

23 = (1/2) * m * 225

23 = 112.5m

m = 23 / 112.5
m = 0.204 kg

Therefore, the mass of the car is 0.204 kg.
