    Conservation of energy / work problem

    30m-0m. Is this how I went wrong when solving algebraically in the image of my working?

    Sorry here it is. Question 9. Thanks!

    Conservation of energy / work problem

    If someone could advise what I've done wrong it would be much appreciated. How have they eliminated the initial and final for y, and simplify only to y? Also, how did they simplify to a positive 2? What algebraic steps have I missed? Thanks for your help.

    Unable to Understand How X2^2 Gets Canceled Out

    Yes it’s just x2 to take out the 1/2 after factoring on both sides then divide by M. I’m more trying to understand why the x is left outside and isn’t inside the radical also. In this one here it’s left outside when usually it’s left inside. Is there a particular reason?

    Unable to Understand How X2^2 Gets Canceled Out

    Am unable to understand how in the final answer the X2^2 gets canceled out without being inside the radical. It doesn’t make sense to me. Any help explaining would be much appreciated as I am stuck. Also am happy to provide more information if needed.

    Newton's Laws — Pushing a box horizontally on a surface

    would say second Law. am I right in stating that it's just as simple as the 12.8 - 11.2N friction then dividing by .490kg mass? which rounded to two decimals equals 3.27m/s^2?

    Newton’s Second Law applied: F=ma

    Thanks for the response. Just started out with physics and trying to wrap my head around it all. The question is basically asking if you double the force and increase the mass by another half then what will acceleration increase/decrease by. My first post on here also and tried to follow the...
