A crate has a mass of 20 kg. What applied force is required to produce an acceleration of 3 m/s2 if the frictional force is known to be 95 N?
asked by yanna
Fnet=Fc-Fmk
ma=Fc-Fmk
(20kg)*(3m/s^2)=Fc-95N
60N=Fc-95N
Fc=155N

A crate has a mass of 27 kg. What applied force is required to produce an acceleration of 3 m/s2 if the frictional force is known to be 98 N? I am confused on how to solve this.
Two crates A and B connected together by a light rope are pulled along a factory floor by an applied force, F. Crate A has a mass of 50 kg and the coefficient of friction (μ) between crate A and the floor is 0,25. Crate B has a
