Question

a cricket ball is free falling from the height of 30 m. then 1. calculate the speed when ball hits the ground and 2. calculate the time to reach the ball to the ground. (take gravitational acceleration g= 10 m/s2).​

Answer 1

Answer:

We know

velocity=√2gh

so v=√2x10x30=√600=10√6 m/s answer

time=displacement/velocity

time=30/10√6=3/√6 second

thanks have a nice day
