The coefficients of kinetic and static friction between the box and the floor are 0.26 and 0.42, respectively Simel the block (box) Express your answer in newtons to two significant figures 110 41D) Figure Incorrect; Try Again; 3 attempts remaining 16 Provide Feedback Next > 77,953 28 29

Explanation / Answer

Normal force on block

N= mg+ F sin x

= 28*9.8+ 16 sin 55

= 287.506 N

Force required to move the block

Fr= uN + 16 cos x

= 0.42*287.506 + 16 cos 55

= 129.93 N

Commemt in case any doubt.. good luck
