Physics

A m1 = 1.95-kg aluminum block and a m2 = 7.85-kg copper block are connected by a light string over a frictionless pulley. The two blocks are allowed to move on a fixed steel block wedge (of angle
πœƒ = 34.0Β°)
as shown in the figure. (For aluminum on steel,
πœ‡s = 0.61
and
πœ‡k = 0.47.
For copper on steel,
πœ‡s = 0.53
and
πœ‡k = 0.36.)

(a) the acceleration of the two blocks

(b) the tension in the string
