The displacement (in centimeters) of a particle moving back and forth along a straight line is given by the equation of motion

s = 4 sin(πt) + 2 cos(πt),
where t is measured in seconds. (Round your answers to two decimal places.)
(a) Find the average velocity during each time period.
(i) [1, 2]

1 answer

avg velocity over [1,2] is just

[(f(2)-f(1)]/(2-1)
Now just plug and chug
