Question

A boy is using a crate to haul a load of bottles up the driveway to his garage. The mass of the crate is
12 kg, the coefficient of friction is 0.24, and the driveway has a slope of 10° from the horizontal. If the
????????????????????????????????????????????????????????????????????????????????????boy can exert a maximum force of 1300 N parallel to the driveway, what is the mass of the largest load
?of bottles he can push up the driveway?
2 cUse g = 9.81 m s .h
[A] 100 kg [B] 590 kg [C] 600 kg [D] 310 kg

Explanation / Answer

L*g*(sin(10)+.24*cos(10)) = 1300
L = 323.2
load of bottles = 323.2 -12 =311.2
nearest value in the options is 310
