Question

stone is dropped from rest from the top of a building 40 4.1 M height it takes 3 second to reach the ground use this information to calculate the value of g​

Answer 1

89.8 m/s is the value of g

Answer 2

Initial velocity = 0

Time = 3

S = 404.1 m

since,

s = ut +1/2at^2

→404.1 = 0 + 1/2(3)^2×g

→404.1 = (9/2) g

→404.1 ×2/9= g

→g = 89.8 ms^-2
