First time posting here. . .
Okay, usually I'm pretty good figuring these type of questions out, but the textbook just doesn't help(no e.g.'s or explanations) and the teacher didn't talk at all about static friction, so, if anyone could give me a hand, I'd be very grateful.
Question:
A sled of mass 50 kg is pulled along snow-covered, flat ground. The static friction coefficient is 0.30 and the sliding friction coefficient is 0.10
b)What force will be needed to start the sled moving?
(Calculated weight is 490N)
