Question

PLEASE HELP!!
acceleration depends on time t therefore a=6t
the body starts from rest .. find the average velocity between t=1 and t=5

Answer 1

wrong answer .. sorry

Answer 2

the correct answer is ....
a=dv/dt=d2x/dt2
solving that you will get x=124
time=4
avg velocity =x/4=124/4
therefore answer equal to 31 m/s ... this is also the answer given by the book ..
