I would appreciate some help for this worksheet question

a) , b) , c) , d)

Explanation:

Mathematically speaking, the instantaneous velocity is the slope of the curve, which can be estimated by means of the definition of secant line, equivalent to the definition of average velocity:

(1)

Where:

, - Position of the particle at and , measured in meters.

- Time, measured in seconds.

Now we proceed to calculate each instantaneous velocity:

a)

b)

c)

d)

where is the circuit diagram ?
