Chapter 16, Problem 20P
A proton and an alpha particle (charge = 2e, mass = 6.64 × 10−27 kg) are initially at rest, separated by 4.00 × 10−15 m. (a) If they are both released simultaneously, explain why you can’t find their velocities at infinity using only conservation of energy. (b) What other conservation law can be applied in this case? (c) Find the speeds of the proton and alpha particle, respectively, at infinity.

Truck suspensions often have "helper springs" that engage at high loads. One such arrangement is a leaf spring with a helper coil spring mounted on the axle, as in the figure below. The helper spring engages when the main leaf spring is compressed by distance yo, and then helps to
support any additional load. Consider a leaf spring constant of 5.45 × 105 N/m, helper spring constant of 3.60 × 105 N/m, and y = 0.500 m.
