Homework Statement
[/B]
A block of mass m1 = 39.2 kg on a horizontal surface is connected to a mass m2 = 21.1 kg that hangs vertically. The two blocks are connected by a string of negligible mass passing over a frictionless pulley. Assume that the horizontal surface is smooth.
(a) What is the acceleration of the hanging mass? (Enter the magnitude only.)
(b) Determine the tension in the cord. (Enter the magnitude only.)
Homework Equations
a={F / m
T= W1 + W2
The Attempt at a Solution
I need to know the acceleration to find the tension and just don't know how to find it. I tried using 9.8 m/s2 but it said it was wrong. I also tried a=(W1 + W2) / 21.1 kg =18.2 m/s2. Not right. I'm getting really frustrated so any help is great
