A block of m 20.0 kg is placed on a plane incline at angle a-37.1 and is connected to a second hanging block with mass m2 by a cord passing over a small, frictionless pulley. The coefficient of kinetic friction between the plane and the block is 0.30. a) Find the mass ma if it is to descend 12.0 m in the first 3.00 s after the system is released from rest. b) Find the mass m, for which the block m, accelerate down the plane at a rate same as the magnitude in (a).
