If it starts moving, that implies that the frictional force is less than 15 N.
To calculate the resistance, you need to know the distance over which the force is applied. Without that information, it's not possible to determine the resistance accurately. Simply saying 20 Newtons doesn't provide enough context.
The difference between 200 newtons and 20 newtons is 180 newtons.
It is the magnitude of the force applied in Newtons or pounds
The net force applied downward to the ground is the combination of your weight and the weight of the backpack, so it would be 450 N + 45 N = 495 N.
To convert Newtons to Joules, you multiply the force in Newtons by the distance in meters over which the force is applied. Joules are a unit of energy, and when you multiply force (in Newtons) by distance (in meters), you get work done, which is measured in Joules.

P=newtons/area... Area is squared... newtons is the stationary form for force.
It is 495 Newtons.

Newton "invented" "applied mathematics" and calculus.

The normal force can be calculated using the equation: Normal force = Weight - Kinetic frictional force. Given that the kinetic frictional force is 40 N, the normal force depends on the weight of the object and additional information is needed to calculate it.
