1. The problem statement, all variables and given/known data Look below for diagram Mass m1is on an inclined plane and weighs 1.00 kg. The inclined plane creates a 40.0 degree angle with the ground, and μk = 0.225. Mass m11 is attached to a weight hanging off the edge via pulley, called M2. M2 has a mass of 1.50kg and hangs from a height h of 50.0 cm. When the system is released from rest, how long will it take M2 to hit the floor? Assume the static frction is exceeded by the weight of M2 2. Relevant equations d=1/2(a)(t2) f=ma (or f = mg) f1 = MgSin∅ f2 = mg a = net force/net weight a = (m2g-m1gsin∅)/(m1+m2) - not sure how this was derived, was in my book 3. The attempt at a solution a=(1.5 kg ) (9.8 m/s2)-(1 kg ) (9.8 m/s2) sin(40) (1 kg )+(1.5 kg ) This solution feels wrong and I'm very sure I did it wrong. Please look it over for me; I'm terribly confused by this problem.
