... A child's pogo stick stores energy in a spring with a force constant of 2.55 x 104 N/m. At position A (XA = - 0.120 m), the spring compression is a maximum and the child is momentarily at rest. At position B (XB = 0), the spring is relaxed and the child is moving upward. At position C, the child i ...

... In both cases your momentum will decrease to zero in the collision. Given that the time Dt of the collision is the same, then the force exerted on YOU will be the same!! If a truck is approaching at 30 mph, then you’d be better off hitting the wall in that case. On the other hand, if it’s only a mos ...
