Question

A box that is 46.83 kg is on a flat surface. The box and surface have a friction coefficient of 0.99. If the box is accelerating to the right, what is the friction force? Answer to the hundredths.

Answer 1

To calculate the friction force, we use the equation:

friction force = friction coefficient * normal force

The normal force is equal to the weight of the object, which is the force of gravity acting on the object:

normal force = weight = mass * gravity

where mass = 46.83 kg and gravity = 9.8 m/s^2 (standard acceleration due to gravity)

So,

normal force = 46.83 kg * 9.8 m/s^2 = 458.766 N

And,

friction force = friction coefficient * normal force = 0.99 * 458.766 N = 453.383 N

So, the friction force is 453.38 N to the hundredths.
