A worker pushes horizontally on a 37 kgcrate with a force ofmagnitude 113 N .The coefficient of static friction between thecrate and the flooris 0.37.
(a) What is the frictional force on thecratefrom the floor? 1 N
(b) What is the maximum magnitude fs, max ofthestatic frictional force under the circumstances? 2 N
(c) Does the crate move?
3
yes no cannottell from the information given
(d) Suppose, next, that a second worker pulls directly upward onthecrate to help out. What is the least vertical pull that willallowthe first worker's 113 N push tomove the crate? 4N
(e) If, instead, the second worker pulls horizontally to helpout,what is the least pull that will get the crate moving? 5N
