Question
A crate of 43.2-{ kg} tools rests on a horizontal floor. You exert a gradually increasing horizontal push on it and observe that the crate just begins to move when your force exceeds 323 { m N}. After that you must reduce your push to 227 { m N} to keep it moving at a steady 20.7 { cm/s}.a.)What is the coefficient of static friction between the crate and the floor? =0.763
b.)What is the coefficient of kinetic friction between the crate and the floor? =0.536
c.)What push must you exert to give it an acceleration of 1.47 { m/s^2}? =291N
d.)Suppose you were performing the same experiment on this crate but were doing it on the moon instead, where the acceleration due to gravity is 1.62 {{ m/s}}^2. What magnitude push would cause it to move? =53.4
e.)What would its acceleration be if you maintained the push in part C?
NEED HELP WITH E!!!
Explanation / Answer
E) if you maintained the push on the moon? on the moon, g is 1.62 friction coefficient will be the same, u= .536 net force= F-u(mg) F= push maintained in part C= 291N 291-u(m g (on moon))= net force 291- (.536)(43.2*1.62)= net force net force/m = net acceleration a= 5.87
