Question

a ball is thrown an initial height of 1 meter with an initial upward velocity of 5 m/s. The ball's height h (in meters) after t seconds

Answer 1

use your kinematics equations to make a function between y & t.

\(y_o\)=1 m
\(v_{yi}\)=5m/s
\(a\)=-9.8m/s^2

Answer 2

You would use this one

\(Δy=v_ot+\frac{1}{2}at^2\)
apply it
\(y=5t+\frac{1}{2}(-9.81)t^2\)
If you are given a diff acceleration other than gravity then use that
