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.
