A 1450kg car drives toward a 60kg shopping cart that has a velocity of -1.2m/s towards the car. The two objects collide, giving the car a final velocity of 5.13m/s, and the shopping cart a velocity of 11.75m/s. What is the initial velocity of the CAR?
A. -5.36 m/s
B. 5.67 m/s
C. -5.67 m/s
D. 5.36 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
