1/4 points 1 Previous Answers WebAssignCalcPhys1 2.P.021 A child operates a remote controlled toy car on a linear track. The figure below plots the car's position as a function of time. x (m) 569 10 Find the velocity of the Joy car over the following time intervals. Indicate the direction with the sign of your answer. (a) From 0 s to 2 s 1.5 m/s (b) From 2 s to 4 s m/s (c) From 4 s to 6s m/s (d) From 6 s to 9s Remember that velocity is the change in position per the change in time. If the graph plots position vs. time, what property of th Think about the initial and final times and positions for each segment. m/s Supporting Materials

Explanation / Answer

velocity = slope = (of the graph

(a)

v = (3-0)/(2-0)= 3/2 = 1.5 m/s

(b)

v = (-0.5-3)/(4-2) = -1.75 m/s

(c)

from time t = 4s to time t = 6 s

the graph is a straight line

the slope = 0

velocity v = 0

(d)

velocityv = ( 0 - (-0.5) )/(9-6) = 0.17 m/s
