Question
a 20kg box is pulled across ahorizontal surface with aforce of 100nt. The coefficient of friction is .3 (a) find the acceleration. (b) how far will the box move in 5 sec. (c) What is the velocity at this time?

Use the coefficient of friction to compute the friction force and the net force. Then use Newton's second law to get the accleration, a.
In time t, it will move (1/2)a t^2. The velocity will be a*t.
