Figure 1 a pulley on top of triangleone block to left of, Ask an Expert

Academics

Figure 1 = a pulley on top of triangle...one block to left of the pulley is2kg .... triangle = 30 degree angle....second block = m

A) Assume that all surfaces in the figure are frictionless. What value should have so the masses won't accelerate? Express your answer to two significant figures and include the appropriate units.

B) Now take mk=0.10 on all surfaces andm=0.50kg. What will be the acceleration of both masses? Express your answer to two significant figures and include the appropriate units.
