a Crate: Static and Kinetic Friction a) In Fig. below, if the coefficient of static friction between the 40.0- kg crate and the floor is 0.650, what is the magnitude of the minimum horizontal force the worker must pull to get the crate moving? N (b) If the worker maintains that force once the crate starts to move and the coefficient of kine friction between the surfaces is 0.500, what is the magnitude of the acceleration of the crate?

Transcribed Image Text:**Title: A Crate: Static and Kinetic Forces of Friction**
**Problem Statement:**
(a) If the coefficient of static friction between a 40.0 kg crate and the floor is 0.650, what is the magnitude of the minimum horizontal force the worker must pull to get the crate moving?
(b) If the worker maintains that force once the crate starts to move and the coefficient of kinetic friction between the surfaces is 0.500, what is the magnitude of the acceleration of the crate?
**Diagram Explanation:**
- The diagram shows a crate on a flat surface with a horizontal force \( F \) being applied by a worker. The force \( F \) is directed to the right. The crate is depicted as a box, and a pull is being illustrated by an arrow pointing to the right. There are no additional details or measurements provided in the illustration.
