上網搵唔到點計重疊的inclined planes
好似呢題咁:
Block X is placed on a smooth inclined plane while block Y is placed on blockX.The mass of X is 2kg and the mass of Y is 0.5kg.The smooth plane is at an angle of 15度 to the horizontal.
b)Then X is released.Y moves together with X without slipping.What is the magnitude and direction of the force acting on X by Y?

屌你老母 個net force咪reaction force of the frictional force + Weight囉 ,點解個答案會係4.74
btw physics呢科好撚on9 個呀sir成日話答案錯 但係佢自己又成日計錯 難分真與假
