a car moves along a straight road in such a way that its velocity (ft/sec) at any time t (in seconds) is given by v(t)=3t√(16-t²) (0≤t≤4)
a. find the distance covered by the car over the time interval [0,4]
b. find the average velocity of the car over the time interval [0,4]

Question

a car moves along a straight road in such a way that its velocity (ft/sec) at any time t (in seconds) is given by v(t)=3t√(16-t²)        (0≤t≤4)
a. find the distance covered by the car over the time interval [0,4]
b. find the average velocity of the car over the time interval [0,4]

anonymous · Answer

okay  I found the distance was 64 feet. just need help finding the average velocity.
