Question

A position-time graph for a particle moving along the x axis is shown in the figure below.

(a) Find the average velocity in the time interval

t = 2.00 s

to

t = 3.00 s.

(Indicate the direction with the sign of your answer.)
.... m/s ?

(b) Determine the instantaneous velocity at

t = 2.00 s

by measuring the slope of the tangent line shown in the graph. (Note that

t = 2.00 s

is where the tangent line touches the curve. Indicate the direction with the sign of your answer.)
... m/s?

(c) At what value of t is the velocity zero?
... s?

Explanation / Answer

a )

V = xf - xo / tf - to

V = 2 -11 / 3 - 2

V = - 9 m/sec

b )

m = dx / dt

= xf - xo / tf - to

= 0 - 13 / 3 - 0

= - 4.33 m/sec

c )

at t = 4 sec

the curve is horizontal..

so at t = 4 sec
