Ball A is projected vertically upwards at a velocity of 16m. s-¹ fron the ground. ignore the effects of air friction. use the ground as zero reference. a) calculate the time taken by ball A to return to the ground. b) draw a velocity time graph for ball A​

Acar of mass m goes around a banked curve of radius r with speed v. if the road is frictionless due to ice, the car can still negotiate the curve if the horizontal component of the normal force on the car from the road is equal in magnitude to 101) a) mv2/r b) mg/2. d) mg e) tan[v2/(eg)]
