Question

If a skier travels at a constant velocity downhill, this means the forces on her are: ................. A. Zero B. Negligible C. Unbalanced D. Balanced

Answer 1

Answer:

F = 0

Explanation:

The net force acting on an object is given by the product of mass and acceleration. We know that acceleration is equal to the rate of change of velocity.

Net force,

F = ma

$F=\dfrac{m(v-u)}{t}$

The skier is traveling at a constant velocity, it means there is no change in velocity i.e. acceleration is equal to 0. Hence, the force on her is 0.
