Question

1.) A hover disc is moving across a wooden floor with a constant velocity and virtually no friction. The soccer

Answer 1

Answer:

The soccer discs will be change.

Explanation:

Given that,

Opposing force = 5 N

We know that,

Drag force :

Drag force is directly proportional to the square of velocity.

$F_{d}\propto v^2$

$F_{d}=\dfrac{1}{2}C\rho Av^2$

Where, C = drag constant

$\rho$ = density

A = area

v= velocity

We need to find what happen to  the soccer discs velocity

According to drag force,

If we applies a force of 5 N opposing the motion of the disc then the velocity of the soccer discs will be change.

Hence, The soccer discs will be change.
