6. [0.2/1 Points] DETAILS PREVIOUS ANSWERS SCALC8 1.4.008. MY NOTES ASK YOUR TEACHER PRAC 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(at) + 4 cos(it), where t is measured in seconds. (Round your answers to two decimal places.) (a) Find the average velocity during each time period. (1) [1, 2] cm/s (li) [1, 1.1] -2.04 x cm/s (ili) [1, 1.01] 14 x cm/s (iv) [1, 1.001] -4 * cm/s (b) Estimate the instantaneous velocity of the particle when t = 1, -4 * cm/s Enhanced Feedback Please try again. When calculating the average velocity, you are actually calculating the slope of the secant line between the two given po
