Hey everyone, I did this question in a past paper and came to mark it but the mark scheme just says correct shape so I dont know if its right or not haha.
If anyone could do it it would be great.

the displacement curve looks like
s = ksinpt + w for 0<= t <= 8 sec
so the velocity would be the derivative...Last edited by the bear; 16-05-2015 at 16:53.

There is a stationary point at t=4 so the velocity curve should cross the time axis there. Since it is also a maximum, the velocity should be positve before t=4 and negative after t=4.
The gradient also looks like it is 0 at t=0 and t=8 so velocity should be 0 there as well.
It looks like it has the steepest gradients at t=2 and t=6, so the highest velocity is at t=2 and the lowest at t=6
