Wrongly called for a foul, an angry basketball player throws theball straight down to the floor. If the ball bounces straight up andreturns to the floor 3.2 s after first striking it, what was the ball'sgreatest height above the floor?

Okay, so in this problem, we have basketball player. They froze a bow into the ground. The boat, the boat bounces up into the air, reaches a maximum height, begins to fall again and heat the ground one more time. This hope prices took 3.2 seconds. Since the movement was divided in two parts. We can say that each part have one point six seconds off time. Okay, So the problem wants to discover what was the maximum height off the bow, the maximum height of the ball. Okay, so let's think what we have in here. We since we want the maximum height, we just need to look to the first part off their movement. And in the first part of the movement, we have the ball going up work with initial velocity, dear friends from zero reaching a maximum height. Were philosophy equals zero. And we know that in this movement, the gravity acceleration is in the opposite direction off the movement. Which means that every time we have a gravity acceleration in the opposite direction, we need to put a minus sign in front of it. Okay, so let's think now we want to discover Duh height. We only have gravity. We have time. We have final velocity. Zero, This is 1.6. His miner's nine. I need you one. And things we want to discover the position did his equation. It seems we want to discover the position and we only have the time. We're going to use the position as a function of time. Jew T Square divided by two. The problem here is that we do not have the initial velocity. So first we need to discover the initial velocity. So then we can discover the position that we want. Okay. How are we going to discover the initials D initial velocity? We use glasses, too, as a function off time. So final velocity zero initial velocity. Miners. Nine point 81 times. 1.6 is his own point to say sh See photos. Does this sink, Emelia? It's simple tools. You Manish
