Question
A m1 = 1.90-kg aluminum block and a m2 = 6.85-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 θ = 35.0°)
For aluminum on steel,
μs = 0.61
and
μk = 0.47.
For copper on steel,
μs = 0.53
and
μk = 0.36.)
The steel block wedge is designed such that the left half of its surface is horizontal while its right half slopes downward, forming an inclined plane of angle θ (measured from the horizontal). A pulley is anchored where the horizontal surface and incline meet. A cord passing over the pulley connects an aluminum block of mass m1 on the horizontal surface to a copper block of mass m2 on the incline.
