Answer/Explanation:
Acceleration is the rate of change of the velocity of an object that is moving. This value is a result of all the forces that is acting on an object which is described by Newton's second law of motion. Calculation of such is straightforward, if we are given the final velocity, the initial velocity and the total time interval. We can just use the kinematic equations. Fortunately, we are given these values. So, we calculate as follows:
acceleration = v - v0 / t
acceleration = (80 mph - 50 mph) ( 1 h / 3600) / 5 s
acceleration = 1.67 x 10^-3 m / s^2

What causes you to miss an object you reach for when looking at it at an angle through two media?
A. The eyes get confusing signals because they are interpreting information from two different places.
B. The brain gets confusing signals because it is used to interpreting light that moves through air.
C. The hands get confusing signals from the eyes because of the change in medium.
Answer: A. The eyes get confusing signals because they are interpreting information from two different places.
Step-By-Step Explanation: I know this is right because it has happened to me, and others multiple times.

i need help i dont have a caculator that need to use for it sadly
Answer:
A) y = 1.3x + 10
Explanation:
2 Points on the graph by using x and y values:
(0, 10) and (10, 23)
Slope:
m= (y2-y1)/(x2-x1)
m= (23 - 10)/(10 - 0)
m= 13/10
m = 1.3
Slope-intercept:
y - y1 = m(x - x1)
y - 10 = 1.3(x - 0)
y - 10 = 1.3x
y = 1.3x + 10
