A 80kg skier has a force of 200 Newtons exerted on him down a slope. Assess whether the slope is less than or greater than 45 degrees.
Weight = mass times acceleration due to gravity
The Attempt at a Solution
The vertical component of his weight is 800 Newton’s approximately. The video showing the problem is actually here in number 2. However the man’s solution doesn’t include all necessary trigonometry I feel.
