Question

Find the speed of a pebble when it is at half distance
of its journey from top to bottom, when it is thrown
horizontally from top of a tower of height 20 m with
initial velocity of 10 m/s is
10/2 m/s
10/3 m/s
20 m/s
25 m/s​

Answer 1

The initial velocity of 10 m/s is 10√3 m/s.

Hence option b is correct answer.
