Question

`h A ball descended along a smooth curve of vertical height h and vertical circular path with radius r velocity according to the total circumference Achieved. Show that the ball will cross the circle if h>5r/2​

Answer 1

Answer:

PHYSICS

A ball is released from height along the slope and move along a circular track of radius R without falling vertically downwards Show that h=

2

5

ANSWER

As the ball is released from a height and moves along a circular track it has sufficient velocity at the lowest point to loop a loop.

At lowest point v=

5gR

Using energy conservation

mgh=
