Explanation:
given,
height of the cliff = 20 m
initial speed = 10 m/s
distance from the edge of the base of the cliff = ?
now,
time taken to cover vertical distance
initial vertical speed = 0 m/s
using equation of motion
t = 2 s
in same time the ball will travel horizontal distance
horizontal velocity of ball = 10 m/s
distance = s x t
d = 10 x 2
d = 20 m
Hence, the correct answer is option A
