problem

[PrudensOptimus]

A woman at an airport is towing her 25.0 kg suitcase at constant speed by pulling on a strap at an angle of above the horizontal (Fig. P5.6). She pulls on the strap with a 30.0 N force, and the friction force on the suitcase is 20.0 N


what is the angle she pulls the suitcase with

wait i got it, it's 48.19 lol simple trig problem.

A light string can support a stationary hanging load of 24.0 kg before breaking. A 3.60 kg mass attached to the string rotates on a horizontal, frictionless table in a circle of radius 0.800 m. What range of speeds can the mass have before the string breaks?

lol i found the answer again...

v = sqrt(235.2*r/m)

Guess this means you need to put a bit more of your own effort into these problems before running for help, huh?
