Q1. A long string is wrapped around a 6.60 diameter cylinder, initially at rest, that is free to rotate on an axle. The string is then pulled with a constant acceleration of 1.70 until 1.30 of string has been unwound. If the string unwinds without slipping, what is cylinder's angular speed, in rpm, at this time?

Q2. An electron is projected with an initial speed 1.10×10^6 into the uniform field between the parallel plates. Suppose that the field between the plates is uniform and directed vertically downward, and that field outside the plates is zero. The electron enters the field at a point midway between the plates.

If the electron just misses the upper plate as it emerges from the field, find speed of the electron as it emerges from the field?
