Pulley Question HELP!
Blocks A and B are connected by a string passing over an essentially frictionless
pulley, When the blocks are in motion, Block A experiences
a force of kinetic friction of magnitude 5.7 N. If mA
5 2.7 kg and mB
5 3.7 kg,
calculate the magnitude of
(a) the acceleration of the blocks
(b) the tension in the string
Fnet1 = Ft1 - Ff1
Fnet2 = Fg - Ft1
Ft1 = Ft2
m1a - 5.7N = m2g - m2a
m1a - m2a = m2g + 5.7N

The Attempt at a Solution
m1a - 5.7N = m2g - m2a
m1a - m2a = m2g + 5.7N
