Question

a body moves with velocity of 2m/s for 5sec then its velocity increase uniformly to 10m/s in next 5sec there after its velocity begin to decrease at uniform rate until it comes to rest after 5 sec . plot a graph and find total distance covered by the body after 2 sec and 12 sec

Answer 2

Answer:

DATA:initial velocity(vi) =2m/s

initial time(ti)=5sec

final velocity(vf)=10m/s

final time(tf)=5sec

totaldistace =vf-vi/(tf-ti)

             =10-2/(5)

=1.6m
