71. assignment (frictional force)

Suppose you have a 105-kg wooden crate resting on a wood floor. The coefficients of static and kinetic friction here are  s=0.5 and  k=0.3.

m = 105 kg

 

(A) What maximum force, in Newton’s, can you exert horizontally on the crate without moving it?

 

(B) If you continue to exert this force once the crate starts to slip, what will its acceleration be, in meters per square second?
