Question

A body starts slipping on a smooth track from point A and leaves the track from point B as shown. The part OB of track is straight at angle 37⁰ with horizontal. The maximum height of body from ground when it is in air is : (g = 10 m/s²)

• A. 16.8 m
• B. 13.6 m
• C. 11.8 m
• D. None of these

Answer 1

Answer: (C)

11.8 m

Answer 2

$v_{B}^{2}$= 2g (H₁ – H₂) = 100 m²/s²

Now, required height = H₂ +$\frac{v_{B}^{2}\sin^{2}\theta}{2g}$= 11.8 m
