A ball is projected horizontally from top of a cliff. The time to hit ground depends on
A. Both velocity and height
B. Mass of ball
C. Height of cliff and g
D. Horizontal velocity
Answer: Option C
Solution (By JKSSB Mock Tests)
Vertical motion is independent of horizontal. t = √(2h/g). Mass doesn't affect. Horizontal velocity affects range, not time of fall. Projectile motion independence of perpendicular components.
