Asmall rubber ball is launched by a compressed-air cannon from ground level with an initial speed of 11.8 m/s directly upward. choose upward as the positive direction in your analysis. what is the maximum height above the ground that the ball reaches? how long does it take to reach the maximum height? how long does it take to reach the ground after it reaches its highest point? what is its velocity just before it hits the ground? (indicate the direction with the sign of your answer.)

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
