NEET 2023 Physics Projectile Motion MCQ Question
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⁻¹. The ball strikes the water surface after 4 s. The height of bridge above water surface is (Take g = 10 m s⁻²):
60 m
64 m
68 m
56 m
Correct Answer
Detailed Explanation
Use the equations of motion to calculate the total displacement of the ball. The height of the bridge is the total displacement minus the initial upward displacement.
