Please help Last question!!!!! Ill give medal and fan you!!!!!!!!!

The function H(t)=-16t^2+vt+s shows the height H(t), in feet, of projectile launched vertically from s feet above the ground after t seconds. The initial speed is v feet per second.

Part A: The projectile was launched from a height of 82 feet with an initial velocity of 60 feet per second. Create an equation to find the time taken by the projectile to fall on the ground.

Part B: What is the maximum height that the projectile will reach?

(Part C and D will be in comments)
