M1 has a mass of 5.61 kg. It is on a horizontal surface, connected by a light string to a hook. Mass M2 can be increased smoothly by adding masses little at a time. The pulley has a negligible mass and no friction.

When M2 is 2.86 kg it begins to accelerate downwards at a rate of 2.34 m/s^2.

What is the static coefficient of friction, and the kinetic coefficient of friction?

- Since the system starts moving when the tension is equal to M2*g, the static coefficient of friction can be found by taking the normal force of M1; Nm1, and dividing Nm1 by M2*g right?
