PHYSICS PROBLEM ABOUT MASS CONNECTED BY A ROPE OVER A PULLEY?

[From: ] [author: ] [Date: 14-04-13] [Hit: ]
When the system is released from rest, mass m accelerates upwards at 2.0 m/s^2.ii) value of m- Because theyre 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.......
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.

NO IDEA....
