The direction of acceleration for the car is given as vertically upward. The correct option is (B).
A vector quantity has both magnitude and direction. It is added using parallelogram law of addition.
The sum of two vector quantities is always a vector quantity.
The sum of two vector quantities can vary from their scalar difference to their scalar addition.
The given diagram shows the force applied on a car in different directions.
Since, the force is a vector quantity, its net value can be calculated as,
In horizontal direction,
400 - 400
= 0
In vertical direction,
450 - 400
= 50
Which implies acceleration in upward direction.
Hence, the car will accelerate in upward direction.

B) 2.4 miles
C) 4.2 miles
D) 12 miles
Answer:
3/8 ÷ 2/5 = 0.9375
18 Quarters and 1 dime/2 nickels
4 quarters = $1.00
4 quarters x 4 = $4.00
2 quarters = 50 cents
$4.00 + 50 cents = $4.50
1 dime = 10 cents
2 nickels = 10 cents
(you can choose to add 1 dime or 2 nickels to $4.50)
B. Y=1/6x
C. Y=-1/6x
D. Y= -6x
Please Explain your answer :)
Is Suzy's answer reasonable?
A.
Yes, it is reasonable because if you add two numbers, you will get a number that is greater than either of the two numbers.
B.
No, it is not reasonable because if you start at –2, you would move 3 places to the left and get –5.
C.
No, it is not reasonable because if you start at –2, you would move 3 places to the right and get +1.
