1. A mass attached to a 50-cm long string starts from rest and is rotated 40 times in 1.00 min before reaching a final angular speed. Determine the angular acceleration of the mass, assuming that it is constant.
W = Delta Theta/Delta Time
Average Acceleration = Delta W/Delta time
W =...
Thanks Doc, i think i understand the concept now however, how could I translate this information into the equation? My take on it is that..the FORCE of one weight would be the variable F
the MASS would be the same (3.00 kg)
and the ACCELERATION would be the variable A minus 9.8 am I correct or...
Hm. So for the 3.0 kg weight, the string pulls up on weight, while the Earth pulls down on it. And wouldn't their accelerations be the same?:confused:
How could I translate this formulaically?
1) Two masses of 3.00 kg and 5.00 kg are connected by a light string that passes over a frictionless pulley as in the figure below. Determine (A) the tension in the string (B) the acceleration of each mass (C) the distance each mass will move up in the first second of motion if both masses start...
no, i cant:cry:
i am a bumbling idiot when it comes to adding vectors and finding components.. am i trying to make right triangles to find each side? i still really don't understand. And could you explain the sin/cos to me as well? my teacher was absent during the whole vector portion

thats the picture.
The question reads "What is the resultant of these two forces?"
My idea is that you would treat the lines like vectors and break it up into components to solve for the resultant. I have been...
Hello all!
My physics teacher has been absent for about two days so i haven't been able to ask him any questions.
Basically I don't understand the concept of relative velocity. I couldn't even start one problem!
