I ended up getting t=4 and y=6. I think it's correct. Thank you for the help.

I know the equation for the maximum height is the same as the first one i gave with ymax substituted in for rfinal and yinitial substituted in for rinitial, but I'm not sure how to find coordinate numbers when two variables are unknown.

How do I find the coordinates for the maximum height of the projectile?

So do I leave the acceleration value as -6t2 or do I solve it further by substituting a value for t? And how do I find the final t value?

So the initial position is -90, initial velocity is 48t and acceleration is -6t2?

Thank you. yi is the initial y position, vi is the initial velocity, and g is gravity due to acceleration.

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...

I think I just have trouble figuring out what I need to solve for and what values to substitute where.

Homework Statement A ball is thrown vertically up from y=0 at time t=0 with vinitial=v0j. Show that the time it takes for the ball to reach the ground is twice the time it takes to reach its maximum height. Homework Equations h=(vi2sinthetai)/2g R=(vi2sin2thetai)/g The Attempt at...
