Question
a body at rest is given an innital uniform acceleration of 8.0m/s-2 for 30s,acceleration reduce to 5.0m/s-2 for d next twenty sec.body mentains speed ten for 60s after brought to rest in 20s draw in graph 1.using d graph to calculate 2.maximum speed attain in motion 3.total distance travel during d first 50s 4.average speed during thesame interval as in (ii)

what is the question you are asking?

1) obviously can't
2) max is at end of 20 second acc
v = vo + at for 1st and second interval
3)x = 1/2(v + vo)t
again for two interval
4) total dist/total time
