2.Im on a physics homework assignment and cant get passed question one, the assignment is a virtual lab the link
b the link is https://phet.colorado.edu/sims/html/projectile-motion/latest/projectile-motion_en.html
and these are the questions
2: Raise the cannon to a height of 15 meters. Set the horizontal velocity to 12 m/sa) Sketch the situationb) Predict the distance you have to place the target from the base of the cannon (calculate this & show all work).
c)Perform the experiment by placing the target at the predicted range and clicking the cannon button. Compare your predicted value to the outcome of the testing experiment. Do they agree or disagree? (Did you hit the target?)
3: Raise the cannon to a height of 5 meters. Measure the distance of the David statue from the base of the cannona) Sketch the situation.b) Predict the velocity with which you have to launch the object in order for it to hit the statue (calculate this & show all work).c)Perform the experiment by entering the predicted velocity and clicking Fire. Compare your predicted value to the outcome of the testing experiment. Do they agree or disagree? (Did you hit the statue?) If they disagree, look at your math again!
4: Set the initial velocity of the object to 20 m/s. Place the target at a range (distance) 20 m.a) Sketch the situation.d) Predict the height from which you have to launch the object in order for it to land on the target (calculate this & show all work).b) Perform the experiment by raising the cannon to the predicted height and clicking Fire! Compare your predicted value to the outcome of the testing experiment. Do they agree or disagree? (Did you hit the target?) If they disagree, look at your math again!
4.I am stuck in a math problem (calculus related rates) and have been stuck for a while. (I’ve been working
working on it since Friday) As it is reading break I doubt that I can cnotact my teacher before it is due.
The question is as following:
A light shines from the top of a pole that is 20 meters high. A ball is falling 10 meters away from the pole, casting a shadow on a building that is 30 meters away. When the ball is 25 meters from the ground it is falling at a speed of 6 meters per second. How fast is the shadow moving?
side note: from left to right it goes lamp, falling ball, wall with shadow.
5.Hi, I have one question on my math homework that I can't seem to figure out. Please help me! Here
is Imagine that in the voting for a certain award, 7 points are awarded for first place, 4 points for second, 3 points for third, 2 points for fourth, and 1 point for fifth. Suppose there were five candidates (A, B, C, D, and E) and 47 voters. When the points were tallied, A had 155 points, B had 173 points, C had 170 points, and D had 154 points. Find how many points E had and give the ranking of the candidates. (Hint: Each of the 47 ballots hands out a fixed number of points. Figure out how many, and take it from there.)
6.I Need a tutor who is experienced in teaching Core plus math course 3. Need explanation and practice of question
of question from the chapter. If the student shows progress it is very likely that we will need at least weekly tutoring.
The Topic is inequalities and linear programming.
Please find attached the material:
-cmic unit is the chapter they are studying,
- Core linear programming is questions on the chapter.
- U2 Exam. will need help in answering the questions:
Please read the material carefully and tell me how much time is needed to make the best use of this time to explain the and go over the examples.
How long it takes to have the student review her work with you.
