how do you find the acceleration for kinetic friction?

4 answers

it totally depends on the problem.
A 25kg object is located on a table near the surfuce of the earth. The coefficient of the kinetic friction between the surfuces is 0.30 and the horizontal force applied is 300n. Can you answer this?
Netforce=mass*acceleration
300N-friction= mass*acceleration
300N-.3*mass*g= mass*acceleration
solve for accleration, you know mass, and g.
thank you so much that was helpful =)
