NEETPhysicsMotion in A PlaneMCQ+4 / −1

A horizontal bridge is built across a river. A student standing on the bridge throws a small ball vertically upwards with a velocity 4 m s−14 \mathrm{~m} \mathrm{~s}^{-1}4 m s−1. The ball strikes the water surface after 4 s4 \mathrm{~s}4 s. The height of bridge above water surface is (Take g=10 m s−2g=10 \mathrm{~m} \mathrm{~s}^{-2}g=10 m s−2 )

Correct answer: B

$$S=u t+\frac{1}{2} a t^{2}$$

NEET 2023 Physics - Motion in a Plane Question 5 English Explanation

$$-\mathrm{H}=4 \times 4-\frac{1}{2} \times 10 \times 4^{2}$$

$-\mathrm{H}=16-80$

$-\mathrm{H}=-64$

$$\mathrm{H}=64 \mathrm{~m}$$
