    Kinematics chasing problem: Car vs. Motorcycle acceleration question

    Im for some reason getting 1.58 s for time. I found 1.75 m as the head start distance and then I do d=d so: 2.45t^2 = 1.75t^2 +1.75 but the answer for "a" should be 6.45s...

    Kinematics Chasing Problem: Correct Answer and Explanation

    I solved this and got 27.3 seconds so basically what I did was found the headtsart of the slower car (15.6 m/s times 6.65 seconds) but the answer given is 33.9 seconds and it uses the second (faster cars speed) to find the head start distance. Which answer is correct and why? Thanks so much

    Standing waves (graphing) homework question

    Thats two wave lengths plus 1/6 of a wavelength

    Standing waves (graphing) homework question

    and just to confirm, when C and B meet, 1/1 T is covered? - (from the very starting position to when C and B have coincided )

    Standing waves (graphing) homework question

    And then when it meets with point A, it further covers 1/4 of T?

    Standing waves (graphing) homework question

    since the wavelength is 6 units and C moves over 6 units to meet B would it just be 1?

    Standing waves (graphing) homework question

    but how would we use a timer if only given a diagram

    Standing waves (graphing) homework question

    Points A b AND C are shown in first diagram Im confused about question three... I feel like its related to wave length but the fractions are throwing me off.

    Waves -- How does increasing tension affect frequency and period?

    Using this stimulation: https://phet.colorado.edu/sims/html/wave-on-a-string/latest/wave-on-a-string_en.html It looks like frequency is decreasing as I increase tension but online it says frequency increases as tension does. Also, I am unsure about what happens to the Period

    Waves - General question about Damping and how it affects a propagating wave

    I think increasing the damping would decrease the amplitude and increase the Period (T). But, what I'm really unsure about is the frequency, wavelength and wave speed. Would it be no effect on those three? Because if dampening acts like friction, wouldn't it slow down the wave/ increase speed?

    General work of friction question

    if the Work done by friction is -4.73 for object #1 but the work done by friction for object #2 is -4.63, in which scenario is the Work greater - the signs are throwing me off. Also, let's say the initial elastic energy of a ball is 5 and its final energy is 0.27 (scenario #1) vs its final...
