Question

I need some help approaching a lab problem

Answer 1

how do i start?

Answer 2

Hi! It looks like you need weight, normal force, kinetic friction force, acceleration, and the speed after 200 meters, and the time it takes to got 200 meters.

\[\sf\Large Weight\]So, the mass of the skier is \(100\ [kg]\)? And gravitation force is \(10\ [N/kg]\)? Well, "weight" is defined as the gravitational force onto the object, so how much gravitational force is on your object? You have \(10\ [N/kg]\) and \(100\ [kg]\), so you can find how many newtons of gravitational force act on your skier with multiplication.

Answer 3

Normal force is the force exerted by a surface that is perpendicular to that surface. Here, it's in response to the weight.
