Prior knowledge questions (do these before using the gizmo.) Two burglars run down an alley at night, trying to escape the cops. Jack is carrying a rigid metal safe. Jill is carrying an armful of antique quilts. In the pitch dark, they both collide headlong into a concrete wall. Who do you think will be hurt more in the collision, and why?
a) Jack, because the metal safe will absorb less energy upon impact.
b) Jill, because the quilts will not provide as much protection as the metal safe.
c) Both will be equally hurt, as their masses are different but the forces experienced will be the same.
d) Neither, because their velocities will cancel out each other's impact forces.
