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?
Remember that a= 9.8 m/s^2.
a. 10.2 N
b. 109.8 N
c. 9800 N
d. 980 N
The force required to lift the loaded bar and overcome the force of gravity can be calculated using the formula:
force = mass * acceleration
Here, the mass of the loaded bar is given as 100 kg, and the acceleration due to gravity is given as 9.8 m/s^2.
So, the force required to lift the loaded bar is:
force = 100 kg * 9.8 m/s^2 = 980 N
Therefore, the correct answer is option d. 980 N.
