Okay i want to know how to do q6
part 1 is ok i got the answer as 4m/s^2
in part ii i got 0.32m but the answer is 0.448m
can some one explain part ii and iii
and the other question is the last question
here it is
A motorcyclist starts from rest at A and travels in a straight line. For the first part of the motion, the
motorcyclist’s displacement x metres from A after t seconds is given by x = 0.6t2 ? 0.004t3.
(i) Show that the motorcyclist’s acceleration is zero when t = 50 and find the speed V ms?1 at this time. [5]
For t ? 50, the motorcyclist travels at constant speed V ms?1.
(ii) Find the value of t for which the motorcyclist’s average speed is 27.5ms?1. [5] >>>>>>>>>>> i want to know how to do this only
i want to know how to do part ii only forst part is ok
Thanx in advance for ur replies
