A high school athlete is in the weight room training for wrestling season. He is trying to bench press a bar loaded with 100 kg. How much force must he exert to lift the loaded bar and overcome the force of gravity?
The correct response is 9800 N. The force required to lift the loaded bar and overcome the force of gravity is equal to the weight of the bar, which is calculated by multiplying the mass (100 kg) by the acceleration due to gravity (9.8 m/s^2). Therefore, the force required is 100 kg * 9.8 m/s^2 = 9800 N.
