Weight is the force of gravity acting on a body. By newton's second law, that force can be calculated as W=mg, where g is the acceleration of gravity, 9.81 m/s^2. So, for the intrepid climber, this would be approximately 88.6 x 10 Newtons or about 886 Newtons.
Answer:
2.77 m/s^2
Explanation:
For simplicity, we will say that the x-axis is parallel to the inclined plane and the y-axis is perpendicular to the inclined plane. The force that the surface applies on the block N will be perpendicular to the plane. The force of friction can be expressed like this:

Where u is the coefficient of kinetic friction.
The x-component and y-component of the weight force will be:

In the y-axis, the acceleration of the block is 0. Then:

In the X-axis, the summation of forces would be:

Pretty sure it's A. 1.5 degrees
Net force can help slow down or stop the motion of an object.
