24.89m

Explanation:

Given parameters:

Force on car = 342N

Initial velocity = 0

Time taken = 12s

Mass of the car = 989kg

Unknown:

Distance covered by the car = ?

Solution:

To solve this problem, we simply use one of the appropriates equations of motions.

s = ut + $\frac{1}{2}$ at²

s is the distance

u is the initial velocity

t is the time taken

a is the acceleration of the car.

To find the acceleration;

Acceleration = $\frac{Force }{mass}$ = $\frac{342}{989}$

Acceleration = 0.35m/s²

Inputting the parameters in the equation:

s = 0 x 12 + $\frac{1}{2}$ x 0.35 x 12² = 24.89m

How does the resultant displacement change as the angle between two vectors increases from 90° to 120°?

user100 [1]

The resultant displacement between the two vectors will increase.

The resultant of the two vectors is given by parallelogram law of vectors.

The parallelogram law of vector addition states that if two vectors are represented in magnitude and direction by the adjacent sides of a parallelogram, the diagonal of the parallelogram drawn from the point of intersection of the vectors represents the resultant vector in magnitude and direction.

The resultant of these vectors, say vector A, and B, is given as;

$R^2 = a^2 + b^2 -2ab.Cos (\theta )$

When;

θ = 90°

$R^2 = a^2 + b^2$

When;

θ = 120°

$R^2 = a^2 + b^2 + ab$

Thus, the resultant displacement between the two vectors will increase.
