toward the left
B.
upward
C.
downward
D.
toward the right
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.
