dk e but for d y cant we use the times found in c, because velocity is a maximum at centre hence cant we just plug those times into d. also need help for e

thanks in advance
Velocity is not a maximum at the centre, speed is. Let me show you why;
At x = 0;
Hence for first two times, let k = 1 , 2:
For (d)
As velocity is maximum at centre, the origin in this context.
respectively for
Hence to find the max velocity, you have to use times with k as an even integer since odd correlates with velocity at a minima . So next time would be at k = 4.
