Section 1: Thought Question of the Week

The Case:  A man screams for over an hour and wakes up the majority of people who live in his neighborhood. Rather than complain about the noise or tell the man to stop, his neighbors give him an enthusiastic response.

 The Mystery:  Who was the man and what four words was he yelling?

Name: Max Mongiello Date: 4-23-2010 Type of posting: 1 Posting: I think the man was yelling, "OH MY GOD.. TWINS!!!!!!!" This because after hearing the news that his wife had given birth to two unexpected twins, he would be extremely excited! His neighbors would give him an enthusiastic response because that is wonderful news and to encourage him to enter his fatherhood with a good attitude.

All the people responded to him enthusiastically because they were watching the same show and were happy to see what happened. He was so happy because he wants the villains to win survivor. He is getting his vocal chords ready for next week because he is going to yell and make a ton of noise. He is excited for next weeks episode of survivor ;)

For the homework I got stuck on the answer for Example 5. The problem was: // //<span style="color: #1cff00; font-family: Arial,Helvetica,sans-serif;">A tennis player's serve travels 180 ft/sec. If she serves upward from 6 feet off the ground, how long will it take for the ball to reach a height of 206 feet? ////<span style="color: #000080; font-family: Arial,Helvetica,sans-serif;">For my answer I got 1.25 seconds and 10 seconds. For the other two problems we ended up with 1 answer. Is it okay if I have two answers or did I get the answer wrong? Please help me. Thank You //**

You did get the right answer because the tennis ball would be reaching 206 feet going up and it would reach 206 feet while falling down. so it is right that you had the two answers.

How are you doing today. I have a question about last night's homework. It's the Vertical Motion Models sheet. For example 6, would it be a dropped or thrown problem. It says the object was propelled from a height of 48 feet with an initial velocity of 32 ft/sec. Does the word propelled mean it was thrown? Or does it mean it was dropped. An answer for this question would be much appreciated. Have a great day.

The answer to your question is that it would be thrown. If it was dropped, it would go straight down. =

== <span style="color: #000000; font-family: 'Comic Sans MS',cursive; font-size: 16px; line-height: 23px;">Posting: Hi! Your substitution is correct. After this, you need to find a GCF. The GCF would be -4. Then you will need to factor but you will find that it is a perfect square. In the end, you will have t= -5/2 and t= 5/2. The answer will be t = 2.5 seconds. ==

Name: Kennedy Clifford Date: 4-22-10 Type of posting: 3 Post: Hey Paige! When finding the X coordinate of the vertex for a normal Quadratic Equation, you need to change the sign of //b// because the formula states **x=-b/2a**, which means that you need the opposite of //b//. Hope this helped.

==**<span style="color: #000000; font-family: 'Comic Sans MS',cursive; font-size: 16px; line-height: 23px;">Posting: Hello Everyone! I don't have a question to ask or answer so I will give you some advice on telling the difference between dropped and thrown. Usually in a thrown problem, it will either say the initial velocity(speed) or will say upward motion. The formula for thrown is: h= -16t^2 + vt + s. You know if it is dropped if it either say downward motion or doesn't say anything about the speed. The formula for that is h = -16t^2 + s. Hope this helped for any one that was confused. **==

I am very sorry, but both your equations were a little mixed up. When doing vertical motion problems the equation for when an object is dropped is h= -16t^2 + s. When the object is thrown the equation is h= -16t^2 + vt + s. I hope this helped!!
