Question

The displacement (in centimeters) of a particle moving back and forth along a straight line is given by the equation of motion s = 5sin(t) + 5cos(t), where t is measured in seconds.

a) Find the average velocity during the time period [1, 2].
cm/s

(b) Find the average velocity during the time period [1, 1.1].
cm/s

(c) Find the average velocity during the time period [1, 1.01].
cm/s

(d) Find the average velocity during the time period [1, 1.004].
cm/s

(e) Estimate the instantaneous velocity of the particle when t = 1.
cm/s

Answer 1

We take the sine of an angle and not of a unit of time. Your function is missing a coefficient for t such as 2pi.
