7) A crate is being pushed horizontally on a flat surface with kinetic friction coefficient µk = 0.28. The push force is 36 N and its acceleration is 1.2 m/s2 , a) Draw a free-body diagram and write both components of Newton’s Second Law. b) Replace into one equation from the other one and solve it to find the crate’s mass.
Homework Answers
b)considering equilibrium of forces along horizontal
ma = F - u m g
m ( 1.2 + 0.28* 9.8) = 36
m = 9.128 kg
