1) Type of motion: constant acceleration.
2) acceleration, a = 9.8 m/s^2
3) time up = time down = 4seconds / 2 = 2 seconds
4) formula = Vf = Vo - a*t^2/2
Vf = 0 => Vo = a*t^2 / 2 = 9.8m/s^2 * (2 s)^2 / 2 = 19.6 m/s
Answer: 19.6 m/s
Answer:
<h2>d=7.2</h2>
Step-by-step explanation:
We can use the Pythagoras theorem to solve for the answer.
step one:
given that the points are located at (x1,y1),(x2,y2) =(3, -6) and (-3,2)

step two:
substituting into the formula we have

To the nearest tenth we have
d=7.2
L' and K' need to be moved to the right one unit but other than that you did it correctly. You'll just have to sort of guess where the top points would be.
Answer:
I hope this helps a little bit.
