Find the force applied to you by the rubber bands?
A giant rubber band is going to launch you straight upwards. Upon launch your acceleration is 15 m/s^2 upwards. If your mass is 70 kg, find the force applied to you by the rubber bands.
This is a copy word from word of the problem. Please be specific. I have a physics test tomorrow.
Thanks!!
Sum the forces acting on you. You have the rubber bands pulling you up and gravity pulling you down.
F = force of rubber bands pulling up on you
mg = force of gravity pulling you down
Using the basic equation F = ma where F is the sum of all the forces acting on you. Replace F in this equation with the sum of the forces.
Fr - mg = ma
Fr = ma + mg
m = 70 kg
a = 15 m/s^2
9 = 9.8 m/s^2
Fr = (70 kg * 15 m/s^2) + (70 kg * 9.8 m/s^2)
Fr = 1736 N (round to two sig figs give 1700 N)
