Referring to the previous illustration, if the boy releases the ball from rest, what will be the radius of curvature of the path at the instant of its release?

Answer»

Solution :The radius of curvature, `r=(V^(2))/(gostheta_(0))`
`theta_(0)`=angle between v & HORIZONTAL = 0, when the ball is released. It STARTS moving horizontally with a SPEED y = speed of the train `10 m//sec`.
`rArr r=(v^(2))/(gcostheta^(@))=((10)^(2))/(g)=10m`
`thetA_(0)`=angle between V & horizontal = 0
