    Use your kinematic equations. Start by writing what you know (initial velocity is 0, time is 0.3 seconds, and distance traveled can be measured from the drawing). Once you know three things, you can use your kinematic equations to solve for the other two (details here: https://www.aplusphysics.com/courses/regents/videos/KinEqns_Reg/KinEqns_Reg.html)

    Welcome Bala!

    Might also consider this recent site, Strategic Option Investing.

    Hi Terry -- based on popular request of instructors I don't give out the solutions to the lab, leaving it to instructors to formulate their solutions (otherwise it becomes a much less effective tool for classroom teachers as students could just copy the answers).

    That's an initial velocity from a jump. Usain Bolt is looking at his whole body running where 12.27 m/s is a sustained speed.
  8. FizziksGuy
    Right, but it's ultimately a proof of 1 vs. 1, not an empirical derivation of g. You're proving something is itself if you use theoretical values.
  9. FizziksGuy
    Graphing the empirical k_delta_x vs. Msintheta would work, but not the theoretical. They want you to determine an empirical value for g, not do a mathematical exercise that results in a 1=1 proof.

    I might start with a resource like this: https://opentextbc.ca/physicstestbook2/chapter/damped-harmonic-motion/ or this: https://www.toppr.com/guides/physics/oscillations/damped-simple-harmonic-motion/

    Hi Muskkan. Damped oscillators are outside the scope of AP Physics 1/2, but happy to help if I can. How far have you gotten so far / where are you getting stuck?
  14. FizziksGuy
    The one about the ice skater? Can you be more specific?
  15. FizziksGuy
    Absolutely... want you to be 100% satisfied with your purchase. Refund complete.
  16. FizziksGuy
    Correct. When you purchase the book it specifically says it cannot be printed (part of the licensing deal with publishers). However, all of the question sets are available to print individually at https://www.aplusphysics.com/courses/regents/worksheets/ws_index.html.
