i don't know why I am stuck on this question. It seems so easy, its making me sick.
question:
A man mounts a bathroom scale positioned on a skateboard such that it can roll without friction down an inclined plane of angle theta. He stands on the scale and reads off his weight as he is rolling down the inclined plane. What is the slope theta of the inclined plane if the scale displays 45kg during the descent and the actual mass of the man is 60kg?
The answer in the back says that theta = 30 degress
can anyone please give me some help with this question
