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.

No.

The pulling force is 5*anglefunction*g

the angle function is either sin or cosine, I dont know how the 40 deg was measured. If it was measured from the vertical, then it is Cosine.

Then

Pulling force = total mass *a

where total mass is 15kg

, or

Then, Equation (1) yields
