Question

the time taken for a ball to drop from its maximum height is directly proportional to the square root of the distance fallen. Given that the ball takes 3 seconds to drop 34.1m find the time for the ball to drop at 15m

Answer 1

=1.99 sec

Explanation:

t=k√d

k= constant

3=k√34.1

3=5.839k

k=0.5137

t=0.5137√15

t=1.99 sec
