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.

2. Game wardens use experiments to help determine the number of fish in a lake. Suppose 80 fish are caught, tagged, and released back into the lake. Two weeks later 120 fish are caught, 3 of which are found to have tags. Using this information estimate the number of fish in the lake.
A. 3,200
B. 600
C. 120
D. 280*****
Answer:
B and 280
B has an opinion. All you need to do is add. You had it right.
2/3*x=1
Find the number which is x
2/3x=1
Multiply both sides by 3/2 to get x by itself
2/3x(3/2)=1(3/2)
Cross out 2 and 3. Divide by 2 and 3. Then becomes 1*1*1*1*x=x
x=1(3/2)
pretend that there is a denominator for 1 which is 1
x=1/1(3/2)
Multiply the numerators together
1*3=3
Multiply the denominators together
1*2=2
Answer:
x=3/2
