Question

a ball is dropped from a tower of height 80m. find the time after which it will hit the ground​

Answer 1

Answer:

Both the balls will take the same time to reach the ground as the time of fall is decided by the velocity along the y acis of motion which is zero in both the cases.

HOPE THIS HELPS

Answer 2

The right option is B.Given, Height = 80m t = 2s So, v = u + g t = 0 + 10 m/s × 2 sec = 20 m/s Where u = 0 So, distance traveled in 2 sec s = u t + 12 ...
