Answer:
The ice chunk will take 2.47 seconds to hit the water.
Explanation:
Height from which ice chunk fell = h = 30.0 m
Initial velocity of the ice chunk = u = 0 m/s
Time taken by ice chunk to cover 30.0 m of height = t
Acceleration due to gravity = g [tex]9.8m/s^2[/tex]
Using second equation of motion ;
[tex]h=ut+\frac{1}{2}gt^2[/tex]
[tex]30.0 m=0 m/s\times t+\frac{1}{2}\times 9.8 m/s^2\times t^2[/tex]
[tex]t=\sqrt{\frac{30.0m/s\times 2}{9.8 m/s^2}}2.47 s[/tex]
The ice chunk will take 2.47 seconds to hit the water.
