Average Velocity

Key Questions

• How do you find the average velocity of the position function #s(t)=3t^2-6t# on the interval from #t=2# to #t=5#?

  Average velocity is defined as total displacement/ total time taken for that

  Given, #s=3t^2 -6t#

  So,displacement in between #2s# and #5s# is #s=3[t^2]_2^5 -6[t]_2^5=3(25-4)-6(5-2)=45m#

  So,average velocity =#45/(5-2)=15 ms^-1#
