Solve 31For 31, assume the sled is the crate in 4 Number 4 is only there to provide context for 31, number 4 is not the question I am asking to be solvedThanks! 4. A factory worker pushes a 30.0-kg crate a distance of 4.5 m along a level floor at constant velocity by pushinghorizontally on it. The coefficient of kinetic friction between the crate and floor is 0.25. a) What magnitude of force musthe worker apply? b) How much work is done on the crate by this force? c) How much work is done on the crate byfriction? d) How much work is done by the normal force? By gravity? e) What is the total work done on the crate?Fa: Uw= F·da. 757.57h. 337.5J07- STInOlesFIF GF F=75Nw=031. Suppose the sled in Exercise 6.30 is initially at rest at x = 0.
