The electrons that produce the picture in a TV set are accelerated by a very large electric force as they pass through a small region in the neck of the picture tube. This region is 1.9 cm in length, and the electrons enter with a speed of 1 × 105 m/s and leave with a speed of 2.5 × 106 m/s.
+33654 Is it the average acceleration that you are after?
If so, use v2 = u2 + 2as where v = final velocity, u = initial velocity a = acceleration and s = distance
Rearrange as: a = (v2 - u2)/(2s)
a=((2.5×106)2−(1×105)2)(2×0.019)⇒a=164210526315789.4736842105263158
This is in m/sec2
