Question

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

disc runs into a baseball, which applies a force of 5 N opposing the motion of the disc. What will happen to
the soccer discs velocity

Answer 1

The soccer discs will be change.

Step-by-step 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)=(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.
