  • A 7kg box with initial speed 12m/s slides across the floor and comes to a stop after 2.4s.

  •  a) What is the coefficient of kinetic friction? 

  • b) How far does the box move?

  • c) You put a 5kg block in the box, so the total mass is now 12kg, and you launch this heavier box with an initial speed of 12m/s along the table. How long does it take to stop?
