A2.0kg solid disk rolls without slipping on a horizontal surface so that its center proceeds to the right with a speed of 5.0 m/s. what is the instantaneous speed of the point of the disk that makes contact with the surface?

Instantaneous speed of contact point will be ZERO

Explanation:

As we know that disc is rolling without slipping on horizontal surface

So here the speed of center of the disc is given as

v = 5 m/s

now at the contact point the tangential speed will be in reverse direction

now we know that net contact speed with respect to its lower surface must be zero

so net velocity of contact point with respect to its lower surface must be ZERO here

the answer is d
