This is a problem in my homework thats due tomorrow please hints?
The Stratosphere Tower in Las Vegas is 921 feet tall and has a "needle" at the top that extends even higher into the air. A thrill ride called the Big Shot catapults riders 160 feet up the needle and then lets them fall back to the launching pad.
a. The height h (in feet) of a rider on the Big Shot can be modeled by h=-16t+v(t) + 921 where v is the initial velocity (in feet per second). Find v using the fact that the maximum value of h is 921+160+1081 feet.
PLEASE HELP IF YOU CAN! we have been solving these kinda of problems but not with two variables!
