Question

A glider of mass m1=12 kg on a frictionless horizontal track is connected to an object of mass m2=5 kg by a massless string. The glider accelerates to the right, the object accelerates downward, and the string rotates the pulley(with mass m=1.6 kg and radius R).

1.Determine the acceleration of the mass 1.

2.Determine the acceleration of the mass 2.3.

Determine angular acceleration of the pulley.

4.Determine the tension T1 in the horizontal part of the string

5. Determine the tension T2 in the vertical part of the string.
