A doghouse has a mass of 98 kg, and the coefficient of friction between it and the ground is 0.95. what is the maximum force of friction between the doghouse and the ground?

The maximum force of friction:

F = μ * N, where μ is the friction coefficient and N id the force of the doghouse normal to the surface.

N for a flat surface would be: N = m*g, where m is the mass and g is the gravitational acceleration = 9,81 m/s².

Combined:

F = μ * g * m
