    Power series solution, differential equation question

    I can not find a solid explanation on this anywhere, so forgive me if this has been addressed already. Given something like y''+y'-(x^2)y=1 or y''+2xy'-y=x, how do I approach solving a differential with a power series solution when the differential does not equal zero? Would I solve the left...

    Conservation of Energy: work done by air resistance on rock

    AH HAH! Man... Now I feel like a complete dumb dumb. THANK YOU so much... I believe you are correct. I shall work it out now. I swear... physics is the easiest thing to over complicate.

    Conservation of Energy: work done by air resistance on rock

    Ah I am sorry. So as the diagram appears, The rock is thrown 4.6 meters above the ground and is traveling horizontally. It then collides with the corner of the box and ricochets off at a 25 degree angle, taking a parabolic path to the ground. I am not sure about the collision. There is a...

    Conservation of Energy: work done by air resistance on rock

    Homework Statement A 250 gram rock is thrown with a speed of 30.0 m/s. It has a speed of 22.5 m/s just before it strikes the ground. Determine the work done by air resistance. There is also a diagram which yields more information. The rocks path is horizontal and it strikes the corner of a...
