An automobile air bag cushions the force on the driver in a head-on collision by absorbing her energy before she hits the steering wheel. Such a bag can be modeled as an elastic force, similar to that produced by a spring.
Calculate the effective force constant k of the air bag for which the bag will prevent injury to a 65.0kg driver if she is 30.0cm from the steering wheel at the instant of impact.
m = 65 kg
x = .3 meters
F = ?
k = ?
F = -kx
F = force
x = displacement(or the distance traveled)
k = the force constant
The Attempt at a Solution
Well I know that this should be an easy solution and I first need to find F, but I do not have a speed that the person is moving. I don't know if I am missing something or if i need to contact the teacher and ask for more information.
Personally I view this as unsolvable without more information, but I just figure that I am missing something.
