Question:

During time of dire emergency, people have been known to lift tremendous weights(physics)?

During time of dire emergency, people have been known to lift tremendous weights ,such as the rear of a car to free a person on whom the car has fallen.Is greater power necessary to perform such feats than when lifting the same car using a jack

Answer:

Probably more power is needed. The same amount of energy is needed, but power is the RATE of energy. When people lift a car in an emergency, they do it faster than when somebody uses a jack.
