Hey all. Sorry for asking so many questions about force, but these are tricky to me! Okay so I have 2 questions that I have started, but have yet to complete. Help would be greatly appreciated.
1. A model rocket weighs 5.4 N.
a) What is its mass?
b) What applied force makes it...
Awesome. Thanks so much for the help! One last one possibly?
A brick has a mass of 1.2 kg. A force of 5.4 N just begins to move the brick along the floor with a constant velocity. What is the coefficient of static friction?
So I would use f=μn
Would that be right...
Hey everyone. Struggling a little bit with a force test I have tomorrow. I've tried a few problems, and don't even know where to begin on another. I have the answers, and I would like to see if they are correct. Thank you so much!
1. An object of mass 70 kg is accelerated by a net force...
I am a bit confused with all this friction stuff... How would I begin to solve this problem and by using what formulas? Thanks.
Suppose a 65-kg boy and a 45-kg girl use a massless rope in a tug-of-war on an icy, resistance-free surface. If the accelleration of the girl toward the boy...
Okay, so this is some trig I learned last year but have since forgotten. If you can give me the first step, I can solve the rest on my own. The given statement is true and you have to prove why using Pythagorean Identities.
csc2\alpha-1 = cos2\alpha
