Homework Help: physics

Posted by Jennifer on Saturday, May 19, 2012 at 11:48am.

An electron ( mass = 9.1110−31 kg) leaves one end of a TV picture tube with zero initial speed and travels in a straight line to the accelerating grid, which is 1.85 cm away. It reaches the grid with a speed of 2.9510^6 m/s . (You can ignore the gravitational force on the electron.)
If the accelerating force is constant, compute the acceleration of the electron. If the accelerating force is constant, compute the time it takes the electron to reach the grid. If the accelerating force is constant, compute the net force that is accelerating the electron, in newtons.
