Homework Help: physics

Posted by Anonymous on Sunday, October 14, 2007 at 11:16am.

Two objects of masses 10.0 kg and 5.00 kg are connected by a light string that passes over a frictionless pulley. The 5.00kg object lies on a smooth incline of angle 40 degrees. Find the accelerations of each object and the tension in the string.

Work:
(10kg)(9.8m/s^2)(sin40)-T=10a
a=4.20m/s^2
T=5a
T=21N

However, the answer is 4.43m/s^2 and 204N.
