Question

A stone dropped from top of well reaches the surface of water in 2seconds,find the velocity of stone​

Answer 1

Explanation:

v = u + at

v= 0 + (9.8)(2)

v = 19.6m/s

mark me as brainliest

Answer 2

Answer:

we know that v equal to u+at

here a is acceleration due to gravity so 9.8

u equal to 0 because the body dropped from a height

time is given 2 sec

v equal to 0+9.8*2

v equal to 19.6 thank follow me
