The rate of deceleration is equal to 25 m/s / 6 s = 25/6 m/s^2.
(a) The string should be angled in such a way that the horizontal acceleration is equal to 25.6 and the vertical acceleration is equal to gravitational acceleration. Using trigonometry,Angle from the vertical = arctan(25/6 / 9.8) = 23.03 degrees.
(b) Since the car is decelerating, one end of the string attached to the car is pulled back and because of the inertia of the object it is goes on the opposite direction and so the object moves toward the windshield.

The units that we should use are gallons per day, we get:
<h3>
Which units should we use?</h3>
We want to express the fact that every day you use 2.4 gallons of gasoline.
So we have two types of units in the above sentence, time (in days), and volume (of the gasoline consumed).
Then we conclude that the units that we should use is volume over time, particularly, gallons per day.
So we can represent that measure as:

4= A because it's greater than or equal to 30 minutes of reading a day and 5 = D because all of the answers are greater than the equation.
Answer:
30
Step-by-step explanation:
you plug in k with 3 and j with 5
4 times 3 + 6(5 – 2) = 30
