The magnitude of the net force acting on the skier can be determined by using Newton's second law of motion, which states that the net force is equal to the product of mass and acceleration.
Given:
Mass of the skier (m) = 75 kg
Acceleration (a) = 1.25 m/s^2
To find the net force, we can use the formula:
Net force (F) = mass (m) × acceleration (a)
Substituting the given values, we have:
F = 75 kg × 1.25 m/s^2
F = 93.75 N
Therefore, the magnitude of the net force on the skier is 93.75 Newtons (N).
It's important to note that the force acting on the skier is influenced by the gravitational force and the component of the force parallel to the slope. The force parallel to the slope is responsible for the skier's acceleration.
