Problem

A bus accelerates uniformly from rest to

u=30 \mathrm{~m} / \mathrm{s}

t=10 \mathrm{~s}

. If another identical bus decelerates from

30 \mathrm{~m} / \mathrm{s}

to rest with the same magnitude of acceleration, compare their displacement-time graphs over 10 seconds. Discuss symmetry or asymmetry.
