Ignore friction and determine an expression for the distance d the boxes travel before coming to rest. Choose the floor as the position for zero gravitational potential energy. (Use the following as necessary: m_1, m_2, v, and g for the acceleration due to gravity.) d = (m_1 + m_2)v^2/2m_2g (b) Is the work done on box 2 by the rope positive, negative, or zero? positive negative zero (c) Determine an expression...
Angular Acceleration of a seesaw problem? help please thanks!
I need help with this problem.thanks so much! show steps!picture related to problem:http://i303.photobucket.com/albums/nn129/wvmounti31/picturenew.jpg1.) Find the angular acceleration alpha of the seesaw?Express your answer in terms of some or all of the quantities m_1,m_2, m_bar, l, as well as the acceleration due to gravity g.Note: the swing bar itself has mass m_bar.2.) In what direction will the seesaw rotate and what will the signof the angular acceleration be?a.) The rotation is in the clockwise direction and the angularacceleration is positive.b.) The...

I'm currently working on a problem and I'm stuck at this step --> I need to get Q to equal 504 from this equation, 0.45V = 0.53V - 0.0592/2 logQ No matter what I try I can't seem to get Q=504 as an answer for that. Please help and explain how you got it! Thank you!! ..I know the first step would be to -0.53 from both sides which gives me -0.08= -0.0592/2 logQ but then I don't know what...

Rotation and Forces Lab Problem An experiment is done to determine the Mol of a pulley. The pulley is in the shape of a disk. The setup is as shown below: lolo The following data are collected: m2 = 1.853 kg; m, = 0.155 kg; r = 5.11 cm. The mass m, is held motionless and released. It is timed as it falls for a distance of 0.350 m ten times. The following times are collected: 1.23 s; 1.35 sec;...

System q1(C) q2(C) F(N) A 16 3 3 B -2 4 2 C 5 -5 5 D 1 2 2 I'm then asked to rank the systems in order of decreasing separation between the charges, and to indicate ties where appropriate. I tried using the equation of F = (k*q_1*q_2)/r^2 and solved for r, but my ranking didn't work. I don't know if I...

1.) Physics General Problem Solving a.) After an average acceleration of 3.25 m/s2 during 2.27 s, a car reaches a velocity of 16.3 m/s. Find the car's initial velocity. b.) A squirrel runs along an overhead telephone wire that stretches from the top of one pole to the next. It is initially at position xi=3.63 m, as measured from the center of the wire segment. It then undergoes a displacement of Δ?=−6.91 m. What is the squirrel's final position xf?

I need help in this problem but not with the physics part, I'm
stuck with the algebra, the book skips some algebra steps and I'me
getting stuck there, I need to understand how they eliminate K and
q3, and also when they are solving for x, what happened to the
other x, if you could do that part doing all the algebra steps I
would appreciate it so much. Thanks
