Solve the all parts of given question:
Question: A 2-kg box sits on a horizontal table. The coefficient of friction between the box and the table is 0.50. The box is pushed to the right with an applied horizontal force of 20 N.
Part A: What is the acceleration of the box?
Part B: If the box starts from rest, how long will it take for the box to travel 10 m?
Part C: If the box starts from rest, how fast will the box be traveling after 3 s?
Part D: What is the acceleration of the box if the horizontal force is 5 N?
I want to know how to work this out step by step, not just the answer please.
