Question

My physics pre-lab is asking me to derive an equation for g in terms of final time (tfinal), height (h), and theta (θ).

Answer 1

See below

Step-by-step explanation:

vf = 0 at max height

vf = vo sin (theta) - g t

vo sin (theta) / t = g where vo = original velocity in m/s

theta is angle of elevation of firing the projectile

g = acceleration of gravity

t is time when at max height
