A 15.4 kg block is dragged over a rough, horizontal surface by a constant force of 182 N acting at an angle of 24◦ above the hor
Dima020 [189]

Answer:

Explanation:

Considering Work done by friction is asked

Given

mass of block m=15.4\ kg

force F=182\ N

inclination \theta =24^{\circ}

block is displaced by s=57.6\ m

coefficient of kinetic friction \mu _k=0.135

Friction force F_r=\mu _kN

Normal reaction N=mg-F\sin \theta =15.4\times 9.8-182\sin (24)

N=76.9\ N

Friction Force F_r=0.135\times 76.9=10.38\ N

Work done by friction force

W=f_r\cdot s

W=10.38\times 57.6=597.92\ N
