Final answer:
The increase in the gravitational potential energy of the car lifted 2.5m off the floor is 23,275 J.
Step-by-step explanation:
The increase in the gravitational potential energy of the car lifted 2.5m off the floor can be calculated using the formula PE = mgh, where m is the mass of the car, g is the gravitational field strength, and h is the height. In this case, the mass of the car is 950 kg and the gravitational field strength is 9.8 N/kg. Plugging in these values, we get PE = (950 kg)(9.8 N/kg)(2.5 m) = 23,275 J.
