A roller coaster is designed such that riders experience "weightlessness" as they go round the top of a hill whose radius of curvature is $20 m$ . The speed of the car at the top of the hill is betweenNEET 2008 (Mains)

Options:

Answer:

Solution:

Actually, $m g - N = \frac{m v ^{2}}{r}$ For weightlessness, $N = 0$ $∴ m g v = \frac{m v ^{2}}{r} = g r = 10 \times 20 ms^{- 1} = 14.14 ms^{- 1}$
