Find the force necessary to start the crate moving, given that the mass of the crate is 32 kg and the coefficient of static friction between the crate and the floor is 0.58.

181.89 N

Explanation:

The force necessary to start the create moving = frictional force.

F = μR ... Equation 1

Where F = Force necessary to start the create moving, μ = coefficient of static friction. R = normal reaction.

But,

R = mg ... Equation 2

Where m = mass of the crate, g = acceleration due to gravity of the plate.

Substitute equation 2 into equation 1

F = μmg ... Equation 3

Given: m = 32 kg, μ = 0.58, g = 9.8 m/s²

Substitute into equation 3

F = 32 (9.8) (0.58)

F = 181.89 N
