ok, this is very simple... I think. Unfortunately my physics book is useless. A brick weighing 24.5N being released from rest on a 1.00M frictionless plane, inclined at an angle of 30 degrees. The brick slides down the incline and strikes a second brick (on a flat frictionless surface) weighing 36.8N a) calculate the speed of the brick at the bottom of the incline. b) if the two bricks stick together, with what initial speed will they move along? c) If the force of friction acting on the two bricks is 5.0N, how much time will ellapse before the bricks slide before comming to rest? I think I could do the problem myself if I knew how to do part A. Any help would be very appreciated.
