Question

A worker pushes horizontally on a 36 kg crate with a force ofmagnitude 112 N . The coefficient of static friction between thecrate and the floor is 0.37.
(a) What is the frictional force on the crate from the floor?


(b) What is the maximum magnitude fs, max of the static frictionalforce under the circumstances?

(c) Does the crate move?
yes
no
cannot tell from the information given



(d) Suppose, next, that a second worker pulls directly upward onthe crate to help out. What is the least vertical pull that willallow the first worker's 112 N push to move the crate?


(e) If, instead, the second worker pulls horizontally to help out,what is the least pull that will get the crate moving?
