A m1=7.47 kg block is placed on top of a m2=11.5 kg block. A horizontal force of 80.3 N is applied to the 11.5 kg block causing it to slide. The 7.47 kg block is tied to the wall by a string. The co-efficient of kinetic friction between all surfaces is 0.172.
a) Determine the magnitude of the tension in the string.
b) Find the acceleration of the 11.5 kg.

a) T - Ff = 0
b) Fnet = ma
The Attempt at a Solution
a) Ff = T
(0.172)(9.8)(7.47) = 12.6 N
I have tried part b) for a very long time, and something is going wrong, can someone help me please!
