Homework Statement
A projectile is launched over level ground on an unnamed planet. The equation of the projectile's vertical position is y(t)=-6t2+48t-90.
a. Determine the acceleration due to gravity on this planet
b. Determine (ymax, tymax), the coordinates of the maximum height of the projectile in the t-y plane
Homework Equations
rf=ri+vit+1/2gt2
The Attempt at a Solution
I know ri=0 because that's the origin
Since I'm not given a time or velocity I'm stuck on how to solve for anything
