For the first part, just put t = 12 in the equation and find s ( displacement = distance).... as for the second part derivate the equation s because the derivative of displacement give the equation of velocity.... at instantaneous rest velocity is always equal to 0, so the equation formed would be 2t – 10 + 10/(1+t) = 0 solve the equation and you would get two values of t 4 and 0. Now the third part requires the equation of acceleration and you can get it by deriving the equation of velocity. The equation you would get is a= 2 – 10/(1+t)^2. Put t = 9 in the equation and you have the answer.......... Hope that helps and good luck for the exam........
It means that xy is the y-axis and 1/x is the x-axis.hey guys, i would like to ask something here. if it's given plot a graph xy against 1/x' does that mean xy is x axis and 1/x is y axis? or otherwise? thanks in advance
here we have to find the distance traveled in the 12th second not 12 seconds, so subtract t=11 form t=12 and you have the answer....
Thank you!
ohmygosh i understandd. Thank youuuSorry my bad.....
