Homework Statement
A block of mass 7.18 kg lies on a frictionless
horizontal surface. The block is connected
by a cord passing over a pulley to another
block of mass 5.6 kg which hangs in the air, as
shown. Assume the cord to be light (massless
and weightless) and unstretchable and the
pulley to have no friction and no rotational
inertia.
Calculate the acceleration of the first block.
The acceleration of gravity is 9.8 m/s^2
Answer in units of m/s
Homework Equations
Fnet=ma
The Attempt at a Solution
I used the equation Fnet=ma to find my horizontal equation T1-T2+M2G=MA
I then reduced that to M2G=MA since the two tensions are the same
After that I plugged in the numbers to get an acceleration of 9.8m/s^2
But i know this answer isn't right because when i checked it it was wrong
