In exercises of unit 1, problem 1B2 question b, it says "Find the time at which the height of the ball is at its maximum height".
I understand that b/32 should be substituted for t in the following formula: s = bt  16t². However, I don't get the result which is b²/64. Can someone please explain how to arrive at this answer? Thanks.

Best ResponseYou've already chosen the best response.0Thanks for your reply. My question is that eventhough I know that the final answer should be b²/64, I don't understand why I didn't get that answer.
