Question

Two toy cars (16kg and 2kg) are released simultaneously on aninclined plane that makes an angle of 30` with the horizontal.Which statement best describes their acceleration after beingreleased? and why?
A) The 16-kg car accelerates 8 times faster than the 2-kgcar.
B) The 2-kg car accelerates 8 times faster than the 16-kgcar.
C) Both cars accelerate at a rate of (0.87)g.
D) Both cars accelerate at a rate of (0.50)g.

Answer 1

Answer:

D

Explanation:

On an inclination of 30°, the acceleration down the inclination will be gsinФ. So the acceleration will be  ⇒

                        g Sin30° = (0.50) g
