A 25 kg object accelerates from rest to a 0.45 m/s in 1.3 seconds. If the coefficient of friction between the object and the floor is 0.15. Find the force that can accelerate it.

Question

A 25 kg object accelerates from rest to a 0.45 m/s in 1.3 seconds.  If the coefficient of friction between the object and the floor is 0.15.  Find the force that can accelerate it.

I don't know how to derieve the formula for this one..please help..

FROM the FORMULA:
-netF=Ff-Fx

bobpursley · Answer

Net force= mass*acceleration You know acceleration (.45/1.3) You know mass friction= mass*g*mu Force-friction= mass*acceleration solve for force.
