Projectile Motion Question

[SOLVED] Projectile Motion Question

1. Homework Statement

a swimmer moving at 1.80m/s dives off a pier and hits the water .80 m from the edge of the pier how high is the pier above the water

2. Homework Equations
Vx=change X /change Time
change Y = Vyi . change Time +1/2 a . (change time)^2

3. The Attempt at a Solution

i found time with the Vx formula to be .44m/s
then i punched it into the change Y formula to get the height of the pier as 0.94 m

im just wondering if i approached it right and by change i mean the displacement triangle i just dont know how to make the symbol sorry

thanks ahead of time

Looks good, but don't round any of your answers until you get your final answer and your time is supposed to be in units of s, not m/s.
