Question

Q A stone is falling freely from the top of a tower. The distance (h) covered in the time (t) taken to fall is given by the formula:

h = 1/2gt square
where g is a constant known as
" acceleration due to gravity".
Find
a) h, when t=2 and t=4
b) h/t for, t=2 and t=4
c) Whether h and t vary directly as each other.
d) Whether h and t square vary directly to each other.​
