    As u did in above part, Fg - Fc = 9.77. So We know Fg = 9.77 + Fc therefore let Fc be any number, the resultant will always be 9.77.

    Amplitude will start decreasing so the curve's amplitude will decrease slightly in each oscillations and come to rest due to damping. Here we are asked to draw for 2 oscillations with the effect of damping, hence the time period will be similar to the orignal graph as damping has no effect on...

    http://studyguide.pk/Past Papers/CIE/International A And AS Level/9702 - Physics/9702_w10_qp_42.pdf Q3(c) explanation with graph required. Is it related to damping thingy? Just correct me, if I am wrong. Due to a slight weight, there will be some damping, so the frequency remains same as...

    Read the question, its mentioned that frequency is now half of the one we measured in (b) so that is 250/2 = 125Hz Now use this frequency, values of x and calculate respective acceleration.

    Acceleration always acts downwards, so its always -ve as ball is thrown upwards against accn of free fall g. :)
