The first box is Acceleration
the second box is Speed
the third box is Speed
the fourth box is velocity
the fifth box is Speed.
The reason the first box is acceleration is because let's say you are about to go up a hill you need to add acceleration to make it up the hill, I was going to say speed but it wouldn't said what mph was.
The reason the second, third,and fifth box is speed is because it is telling up that an object is going _mph (the blank is where you put your estimate of speed of an object).
The reason the fourth box is velocity is because velocity is both magnitude and direction so in the fourth box it says that the race car made a slight left turn which is a direction that the car is going in.
Hope this helped :)
Have a great day

Answer:
Explanation:
From the question we are told that
Speed of man
Speed of wind
Generally the Relative wind speed V_R is mathematically given directly as
Therefore the relative wind speed will the person sense
Answer:
Explanation:
Givens
d = 8.5 meters
vi = 0
a = 9.81
t = ?
Formula
d = vi * t + 1/2 a t^2
Solution
8.5 = 0 + 1/2 9.81 * t^2 multiply both sides by 2
8.5 = 4.095 t^2 Divide both sides by 4.095
8.5/4.095 = t^2
1.7329 = t^2 Take the square root of both sides
t = 1.316
It takes 1.316 seconds to hit the ground.
