1. a box has a mass of 100kg, and the second has a mass of 55kg. there is a rope between them that attaches them. theres a rope connecting to the first box, that is pulled with a force of 200N at 50 degrees above the horizontal. the box os moved 305cm for 5s

a) what is the frictional force on the boxes

b) what is the tension in the rope joining the two boxes

2.

a rope is hanging off the side of the table. the rope is 2m long. the coefficient of friction between the table and the rope is 0.62

what is the maximum length of the rope that can hang over without slipping?

2. Relevant equations

1. i tried using d=vy1*t+0.5g*t^2 to find a. if i assumed vy1 is 0 because it starts from rest. then tried using Ef=Fappy-Ffs to find the mui in FFs...

2. Have no idea how to start

3. The attempt at a solution

have no idea o-o'' what to do ><"
