1. The problem statement, all variables and given/known data 1)A 3.0kg chair at rest is pulled across the floor by a 20N force.If the co-efficient of friction between the floor and chair is 0.25, calculate: a)the net force on the chair. answer=13N b)the displacement of the chair after 2.0sm answer=8.4m 2. Relevant equations Fn=m*a Fn=Fa+Ff Fg=m*g Ff=m*FT(flipped for perpendicular) V2=V1+a*t d=V1t+1/2a*t^2 3. The attempt at a solution I cnat get it started like Im lost with what equation to pick.
