An automobile having a mass of 480 kg is driven into a brick wall in a safety test. The bumper behaves like a spring of constant 6.49 × 106 N/m and compresses 4.62 cm as the car is brought to rest. What was the speed of the car before impact, assuming no energy was lost during impact with the wall? Answer in units of m/s

It may seem strange that the selected velocity does not depend on either the mass or the charge of the particle. (for example, would the velocity of a neutral particle be selected by passage through this device? ) the explanation of this is that the mass and the charge control the resolution of the device--particles with the wrong velocity will be accelerated away from the straight line and will not pass through the exit slit. if the acceleration depends strongly on the velocity, then particles with just slightly wrong velocities will feel a substantial transverse acceleration and will not exit the selector. because the acc
