    1-D Kinematics Problem

    Even if it's quadratic, why wouldn't you be able to solve for t?

    Why can't you solve for t?

    Free-fall gravity problem

    Yes, when the object is in freefall on Earth, gravity = a = 9.8m/s^2 down. Signs are optional but you could say -9.8n/s^s. In 2D, the gravity is always 9.8m/s^2 down on the object. It doesn't matter how the object is moving or thrown, gravity is always down.

    Acceleration due to Gravity

    Hitchhikers reference eh? The other object should be the falling whale.

    Finding rate of magnetic field PLEASE HELP!

    Oh I see. Thanks for setting me straight. I'm still learning and your opinion is very helpful to me.

    Finding rate of magnetic field PLEASE HELP!

    Area of wire, cross section area.

    Finding rate of magnetic field PLEASE HELP!

    Well, circumference=pi*diameter, lol 102 turns = 102 circumferences

    Kinematic graphs

    The graph of the acceleration is the graph of the derivative of the v-graph. Find the slope at each second and graph it onto a new graph. The a-graph is not linear.

    Finding rate of magnetic field PLEASE HELP!

    Isn't the L for B=UIN/L the length of the solenoid not the length of the wire?

    Conservation of Energy max height

    Break the velocity into components.

    Kinematics Problem

    Yes, i know.

    Kinematics Problem

    Wait, I think it was the d for the 4th second, from 3-4s. Because the first second is 0-1s, second second is for 1-2s, etc. So Vf=vo+at V@3=5+9.8*3 and V@4=5+9.8*4 Vf^2=Vo^2+2ad (V@4)^2=(V@3)^2+2*9.8*d Find d

    Kinematics Problem

    Well, d=Vot+.5at^2 so d should be 98.4m. Did you get that?
