A 15 kg mass is attached to a chord that is wrapped around a wheel with a radius 10.2 cm. The acceleration of the mass down the frictionless incline is .84 m/s^2. Assume the axle of the wheel to be frictionless. Find the force in the rope. The acceleration due to gravity is 9.81 m/s^2. Answer in units of N. Ok so I don't truly understand how to approach this problem. Since it is part of my homework having to deal with torque, I feel that torque should have something to do with it, but I can't figure out how to relate it. If I don't use torque, can I just say that: F=ma? and if so, I understand that my mass is 15 kg. But my acceleration, how would I take that into account since it is on an incline of 38 degrees (sorry, it has a picture but it will not cut and paste for some reason.) If anyone has any suggestions of how to approach this problem or how to find the acceleration, that would be great!
