Hi guys :) I have a question here and I really hope you can help.
A 5.00 kg block on a 30 degree incline is connected by a light string over a frictionless pulley to an unknown mass , m. The coefficient of kinetic friction between the block and the incline is 0.100. When the system is released from rest, mass m accelerates upwards at 2.0 m/s^2.
Find
i) String tension
ii) value of m

Because they're connected by a string, if mass m accelerates upwards at 2 m/s^2, then the 5kg mass is accelerating down the incline at 2 m/s^2.
Diagram and calculate all the other forces on the 5 kg block, then solve for tension given this acceleration.
You will probably want to angle your x-axis along the incline, so that only gravity has both x and y components.
The same tension is applied to mass m. Diagram the forces on this block, and calculate the net force. Solve for the mass that would have the given acceleration.
