an object moves along x axis such that its velocity varies with time as v=(50-10t) where t is time in seconds average speed of the particle in the time interval t=0 to t=6s is equal to

Answer 1

recall that the average value of f(t) on the interval [a,b] is

∫[a,b] f(t) dt
-----------------
b-a

this works here because v is always positive in [0,6]
