The horizontal pushing force required to on slide the crate throughout the dock at a continuous speed is

You are watching: A 60 kg crate rests on a level floor

**241 N.**

**Explanation****:**

**coefficient of static friction**we have:

μ

= ,where,

is the**horizontal pushing force,**

W = mg is the **weight the the crate** directed downward,

is the

**static friction force-directed**opposite to the horizontal advertise force and also equal come it,

N is the **force of reaction **directed upward and also equal to the weight of the crate.

From this formula us can uncover **the horizontal pushing pressure required to just start the crate moving:**

= 0.760

60 kg 9.8 m / s^2= 447 N.

By the**definition the the coefficient of kinetic friction**we have:

u

,where,

is the**horizontal advertise force,**

W = mg is the** weight of the crate** directed downward,

is the

**kinetic friction force-directed**opposite come the horizontal pushing force and equal to it,

N is the **force that reaction** command upward and equal come the load of the crate.

From this formula we can discover the** horizontal pushing force required to on slide the crate throughout the dock in ~ a consistent speed:**

= 0.410

60 9.8 = **241 N**.

**start the crate moving**is

**447 N.**
