Question

A stone dropped from a tower reaches the ground in 5 s.Calculate the velocity with which it will hit the ground?(g=9.8 ms square)​

Answer 1

Answer:

Here    Initial velocity (u) = 0

Final velocity (v) = 58.8 m/s

Time (t) = 6 seconds

We know v=u+at

58.8=a×6

⇒6a=58.8

⇒a=658.8

∴a=9.8m/s2

∴ The value of acceleration due to gravity = 9.8 m/s
