I guess I'm assuming that the acceleration of the mass is the same acceleration as the cylinder, is that correct?

A massless string is wrapped around a solid cylinder. A block of mass m=2.0 kg hangs from the string. When released, the block falls a distance 82 cm in 2.0 s. Calculate the mass of the cylinder. Okay, for this problem, I started off with drawing free body diagrams for the block and the...

okay, okay is this correct? haha Fty=mg and Ftx=ma Thanks for the help by the way.

sorry, Ft - force of the tension.

So would this be the correct formula?: Ft+mg=m v/r

I thought that because the string is horizontal there is no gravity acting on it. How do I calculate the centripetal force too?

Homework Statement A 100g bead is free to slide along an 80cm long piece of string ABC. The ends of the string are attached to a vertical pole at A and C, which are 40 cm apart. When the pole is rotated about its axis, AB becomes horizontal. Find the tension in the string. Find the speed...

I get a negative value for t if I do this and a positive value the other way.. is my algebra just off? Thanks for the help.

Could you tell me why it is t2+1 instead of t1+1? I'm just thinking that because the stone is thrown up one second later. As in ball=t stone=t+1 ? are you saying it's the other way around?

I'm sure this is an easy question but I just can't seem to understand which equations I need to use. A ball is thrown vertically upward with an initial speed of 11m/s. One second later, a stone is thrown veritcally upward with an initial speed of 25 m/s. Find the time it takes the stone to to...
