Question

In the figure below the two blocks are connected by a string of negligible mass passing over a frictionless pulley. m₁ = 10.0 kg and m₂ = 5.50 kg and the angle of the incline is θ = 39.0°. Assume that the incline is smooth. (Assume the +x direction is down the incline of the plane.)

(a)

With what acceleration (in m/s²) does the mass m₂ move on the incline surface? Indicate the direction with the sign of your answer.

(b)

What is the tension in the string in newtons?

(c)

For what value of m₁ (in kg) will the system be in equilibrium?
