Question

Acceleration Stuff :)

Answer 1

someone help me with how i can find acceleration due to gravity

Answer 2

You can get an approximate value by dropping an object from a building of known height and measuring the time it takes to hit the ground

Answer 3

ok i know the time and the height can we do an example

Answer 4

T=1.01
H=7.57m

Answer 5

use one of the equations of motion for uniform acceleration

s = (1/2)a t^2 where s = height , t = time and a = acceleration due to gravity
so we have
7.57 = (1/2)a (1.01)^2

solve for a.

Answer 6

i thought a is 9.8

Answer 7

yes it is

Answer 8

oh i get it

Answer 9

on earth it is 9.8

Answer 10

9.8 ms-2
