    My bad ... got it. Thanks :)

    What is the Phase Constant in an Inelastic Collision with a Spring?

    Alright, I usually use the expression x=Acos(ωt+ø) How do I find the phase constant in this case?

    Thank you. now I understand that it can't be ∏ because the question said to set the lowest point as x=0. But I still don't understand how to find phi_0 . I have serious trouble with determining phi_0 LOL

    What is the Phase Constant in an Inelastic Collision with a Spring?

    Thank you ! For some reason it didn't click for me that SHM occurs next. I have one more problem though. I find it very challenging to find the phase constant (Φ0) can you please tell me how to find it in this case. It looks like zero to me because the spring was neither streched nor compressed...

    Also, Fs1 is missing because it passes through the pivot. So the torque it's producing is equal to zero. If you want to show me a better approach please do. Thanks :)

    Balancing a plank on springs (Torques)

    Hey ! I thought I am following it. I am sorry if I didn't. Ok .. I multiply 430 by 9.8 and divide the product by 3700. Δx is the compression of the springs.

    Balancing a plank on springs (Torques)

    Can't I just use one pivot ? Hey ! I was wondering why do I need to consider both ends? The object has one pivot.

    What is the Phase Constant in an Inelastic Collision with a Spring?

    Well, so (m1+m2)v2 = initial momentum but what happens to energy? or shall I just say that v2 will stay the same and then multiply it by 3 seconds to get the distance ? Why does the question give info about the spring then?

    I thought lowest point means x = A. But I chose to make down as negative, so would this make x = -A ?

    What is the Phase Constant in an Inelastic Collision with a Spring?

    I have struggled with this question. I don't understand what do especially that the question says inelastic but there is a spring. A mass of 12 kg is sliding along a frictionless surface at a speed of 5 m/s. It collides perfectly inelastically with a stationary mass of 24 kg which is attached...

    Balancing a plank on springs (Torques)

    Hello, I would like some help with the following question. I highly appreciate your help ! I got an answer that doesn't make sense so I know there must be a concept that I don't get. There is a complicated piece of machinery sitting on a plank of metal which is 2 m long. The metal and...

    Energy and oscillations combined

    Hello, I would like some help with the following question. I highly appreciate your help ! A mass falls freely for 2.0 m before it hits a vertical spring. The mass sticks to the spring, and the system begins to oscillate with a period of 2.2 seconds. If you start a stopwatch when the mass...
