Question

a 1 kilogram rubber mass is released from rest at the very top of a rough incline as shown. the mass slides and finally reaches the bottom 2.9 seconds later. what material might the incline be made out of?

Answer 1

The material of the incline can be determined based on the motion of the rubber mass. Since the rubber mass is sliding and not rolling down the incline, it indicates that there is friction between the mass and the incline, making it a rough incline.

Step-by-step explanation:

The material of the incline can be determined based on the motion of the rubber mass. Since the rubber mass is sliding and not rolling down the incline, it indicates that there is friction between the mass and the incline, making it a rough incline. The material of the incline can be any rough material such as rough concrete or rough wood.
