3.1.2 quiz: newtons laws of motion\na skier is traveling fast down a mountain slope. the table shows data collected on the skier at a particular instant.\nmass 64 kg\nweight 608 n\nvelocity 21 m/s, forward\nforce of friction between skis and snow 6 n, backward\nforce of air resistance 0.5 n, backward\nwhich values affect the net force on the skier?

Answer

Explanation:

Step1: Recall net - force concept

Net force is the vector sum of all forces acting on an object.

Step2: Identify relevant forces

Forces that act in the direction of motion or against the motion of the skier affect the net - force. Mass and weight act vertically (weight is the force due to gravity acting on the mass), and do not directly affect the horizontal net - force along the slope. Velocity is a kinematic quantity and not a force. The force of friction between skis and snow and the force of air resistance act in the backward direction (opposite to the motion of the skier), and thus affect the net force on the skier.

Answer:

Force of friction between skis and snow, Force of air resistance
