Dude Ive been through half of my universities physics classes... I'm serious especially if its a free body, torque, equation of motion, or any circuits problems.

ok. here it is. theres a diagram so im gonna have to explain that first. i'll love anynoe that helps

diagram:
Mass A (a block) sits on a frictionless surface. it is attached by a rope that is attached to a pully at the end of the surface. Mass B (different block) hangs on the other end of the pully of the side of the surface.

a) if Mass A = 13.0 kg and Mass B = 5.0kg, determine the acceleration of each block. b) If initialy Mass A is at rest 1.25m from the edge of the surface, how long does it take to reach the edge of the table if the system is allowed to move freely? c) if Mass B = 1.0kg, how large must Mass A be if the acceleration of the system is to be kept at 1/100g?

this is shitty. thanks in advance for anyone who tries or even looks at the problem. +K to all

once you take a real physics class youll realize that AP physics is a joke

if your book is called physics and its by glencoe, its on hotmath, and I may still have an account for that.

I pretty much gave you everything you need to get started... I didn't solve it for you cuz that way you wouldn't learn anything... PM if you need more help

X=Xo+Vot+1/2at^2 for question b I believe

or maybe its V^2=Vo^2+2a(X-Xo)

For the acceleration, I think you find the force of gravity or something like that. If I think of it I'll post back

Once you find the acceleration, this problem is super easy

acceleration was solved in the first problem... you just plug and play with one of the motion equations.. look em up in your book or wikipedia
