Two blocks of masses m1, and m2, resting on frictionless inclined planes, are connected by a mass- less rope passing over an ideal pulley. Angle φ = 45.0° and angle θ = 36.9°; mass m1 is 6.00 kg and mass m2 is 4.00 kg. (a) Using energy conservation, find how fast the blocks are moving after they travel 2.00 m along the inclines. (b) Now solve the same problem using Newton’s second law. [Hint: First find the acceleration of each of the blocks. Then find how fast either block is moving after it travels 2.00 m along the incline with constant acceleration.]
