Net Force and Applied Force: Calculating Acceleration and Friction Coefficients

[Verbally]

Homework Statement

1.) An 11 kg block is being pushed forward on a flat surface with a force of magnitude 45 N. The coefficient of kinetic friction is 0.12 and the coefficient of static friction is 0.15. What is the acceleration of the object, and what is the net force acting on the object?




2.) A 12 kg box is on the surface of the moon. The coefficient of static friction between the box and the surface is 0.25. How much force is needed to get the box moving?



-I'm just a little confused on how to put all of it together, I know bits and pieces, but a solution would be nice so I can refer back to it later. - Thanks

Hello, Verbally, welcome to Physics Forums!

As a newbie, you probably just glimpsed over the rules, which require you to list relevant equations and show an attempt at a solution before we can offer help. Solutions are not provided in this forum.

Try to identify all the forces acting on the block or box, and apply Newton's laws. Someone will then be glad to assist.

Thanks!
