First step: Convert 24kg to Newtons by multiplying by gravity, or 9.8. You get 235.2 N Next: F = m*a If you draw a free body diagram, you will notice that the Net Force is equal to the Applied Force minus the Frictional Force. Frictional Force is Ff = μ * Fn Ff = .23 * 235.2 585 - 54.096 = 24*a 530.904 = 24*a a = 22.121 m/s Let me know if any of this doesn't make sense.
