I can't fail this test, or I won't pass the class. Please just try to help me with this math problem. Please. You toss a ball into the air at a height of five feet. The velocity of the ball is 30 feet per second. You catch the ball six feet from the ground. Use the model
6=-16t^2+30t+5
to find how long the ball was in the air.
I really don't have any idea how to solve this problem. Help?
