Question
Two blocks are connected by a light string that passes over a frictionless pulley as in the figure below. The system is released from rest whilem2is on the floor andm1is a distancehabove the floor. (a) Assumingm1>m2, find an expression for the speed ofm1just as it reaches the floor. (Use any variable or symbol stated above along with the following as necessary:g.)(b) Takingm1=6.0kg,m2=3.9kg, andh=3.8m, evaluate your answer to part (a).

(c) Find the speed of each block whenm1has fallen a distance of1.1m.

Explanation / Answer
(a) v = {2*h*g*(m1 - m2)/(m1+m2)} ^ 0.5 (b) v = 3.99 m/s
