Find out the velocity of m1

Reference no: EM137826

Q1. In the Atwood machine shown below, m1 = 2.00 kg and m2 = 8.00 kg. The masses of the pulley and string are negligible by comparison. The pulley turns without friction and string does not stretch. The lighter object is released with a sharp push that sets it into motion at vi = 2.20 m/s downward.

How far would m1 descend below initial level?

Find out the velocity of m1 after 1.8s.

Q2. A small but measurable current of 1.2*10^-10 A exists in a copper wire whose diameter is 2.5mm compute the current density and the electron drift speed.
