Solve the wave equation utt = uxx subject to boundary and initial conditions of the form u (0, t) = 0 ux (1, t) = 0 u (x, 0) = 0 ut (x, 0) = 1. This would describe a string that is attached to something on the left side, connected to a frictionless hoop/rail system on the right side, and suddenly hit from below in such a way as to impart a constant velocity to the string.

The great sandini is a 60.0-kg circus performer who is shot from a cannon (actually a spring gun). you don’t find many men of his caliber, so you him design a new gun. this new gun has a very large spring with a very small mass and a force constant of 1100 n/m that he will compress with a force of 4400 n. the inside of the gun barrel is coated with teflon, so the average friction force will be only 40.0 n during the 4.00 m he moves in the barrel. at what speed will he emerge from the end of the barrel, 2.50 m above his initial rest position?
