A worker pushes horizontally on a 37 kg crate with a force of magnitude 115 N. The coefficient of static friction between the crate and the floor is 0.37. What is the frictional force on the crate from the floor? N What is the maximum magnitude fS, max of the static frictional force under the circumstances? N Does the crate move? yes no cannot tell from the information given Suppose, next, that a second worker pulls directly upward on the crate to help out. What is the least vertical pull that will allow the first worker's 115 N push to move the crate? N If, instead, the second worker pulls horizontally to help out, what is the least pull that will get the crate moving? N
