Inclined Angular acceleration?

Question

There is a simple sled at the top of a frictionless inclined plane that makes an angle of 32 degrees from the horizontal. Working in the metric system, calculate

(a) the component of the acceleration of gravity parallel to the slope and

(b) the component of acceleration of gravity perpendicular to the slope.

How do I do this? Thanks.

Answer 1

Use a bit of trig

Parallel is g*sin(32)
Perpendicular is g*cos(sin(32)
