I believe the answer is H for when you bounce it, it has stress when it hits the floor and then goes up giving it kinetic
Answer:
∆h = 0.071 m
Explanation:
I rename angle (θ) = angle(α)
First we are going to write two important equations to solve this problem :
Vy(t) and y(t)
We start by decomposing the speed in the direction ''y''
Vy in this problem will follow this equation =
where g is the gravity acceleration
This is equation (1)
For Y(t) :
We suppose yi = 0
This is equation (2)
We need the time in which Vy = 0 m/s so we use (1)
So in t = 0.675 s → Vy = 0. Now we calculate the y in which this happen using (2)
2.236 m is the maximum height from the shell (in which Vy=0 m/s)
Let's calculate now the height for t = 0.555 s
The height asked is
∆h = 2.236 m - 2.165 m = 0.071 m
Answer:
No!
Explanation:
The correct answer is x = 9.
If a man is standing more than one focal length away from the focal point of a concave mirror, the image form in the mirror will be "Upside Down." Since the the distance of the man standing is more than one focal length away from the focal point, given that it is a concave mirror, then for sure, the image will be upside down.
