    Pulley system and energy conservation?

    Yes, it's 2 meters. Now I understand. Actually, I think I figured it out. would you mind taking a look?

    Pulley system and energy conservation?

    wouldn't it be the vertical height of 3 m?

    Pulley system and energy conservation?

    Ok. And how would I write the height change for block A. Would it simply be the hypotenuse of the incline? 5 ?

    Pulley system and energy conservation?

    ok, so would I have terms for each block i.e. kinetic energy initial for Block B and A, kinetic energy final for B and A, potential energy initial for block A and B, potential energy final for block A and B?

    Pulley system and energy conservation?

    I thought that I should treat the blocks as one system: When Block B loses potential energy, Block A gains potential energy. So, Block B has potential energy and final kinetic energy, but Block A only gains final potential energy. Is this not the correct interpretation? How should I write this...

    Pulley system and energy conservation?

    Homework Statement [/B] Two blocks are connected by a string that passes over a massless, frictionless pulley, as shown in the figure. Block A, with a mass mA = 4.00 kg, rests on a ramp measuring 3.0 m vertically and 4.0 m horizontally. Block B hangs vertically below the pulley. Note that you...

    Projectile motion of tabletop ball?

    Hello, I know I asked this question a while ago, but I'm looking over my latest threads in order to review for a physics exam i'll be taking soon. I think I understand this problem, but would you mind explaining part b.) again please. How is it that I can solve for the total flight time of...

    Calculating Forces and Kinetic Friction for a System of Connected Blocks

    wonderful! And the answer is indeed correct ( I just inputed it into my online homework). Thank you both for your help. I look forward to your assistance with future problems.

    Calculating Forces and Kinetic Friction for a System of Connected Blocks

    Ok, thank you, that makes sense; hopefully I got your point. Here is my revised work; does it look better now? Note: Block A is the small block, Block B is the big block

    Calculating Forces and Kinetic Friction for a System of Connected Blocks

    yes, so sorry, I forgot to include the second part of the problem :nb)If the value of m is 260 g, what is the value of F? and, I think I understand what you're saying. Would the vertical forces simply not be included in the equation because they cancel out (normal force and force of gravity...

    Calculating Forces and Kinetic Friction for a System of Connected Blocks

    Thanks for the complement. Unfortunately, I'm not exactly sure what you mean. Did I not add the forces like vectors? I indicated whether they are moving in the positive or negative direction in the equation and in the diagram (I even drew a little coordinate plane next to the FBDs in order to...

    Calculating Forces and Kinetic Friction for a System of Connected Blocks

    Hi everyone, I'm having a difficult time figuring out this problem. Could someone give me some pointers? I set up the equations and the free body diagrams (hopefully they're correct) ; all I have to do now is solve for F.1. Homework Statement A block of mass m is on top of a block of mass M =...
