- Block A Incline C Loop H R 20 Cm B D A Children S Toy Shown Schematically Above Consists Of A Frictionless Block Of 1 (100.85 KiB) Viewed 41 times
block A incline C loop h R = 20 cm B D A children's toy, shown schematically above, consists of a frictionless block of mass m = 50 grams which slides down an incline then around a loop of radius R = 20 cm and then along the flat section to the right. The path of the block is ABCBD. In this question the block is released from rest at point A. All losses including those due to drag and surface imperfections can be neglected. a) What is the minimum velocity that the block must have at point C in order that it not fall off the track? [10 marks] b) What is the minimum height h of point A so that the block makes it around the loop without falling off the track? [10 marks] c) What is the velocity of the block at point D? [5 marks]
