Answer :
Answer:
The average velocity of the car is 32 m/s.
Explanation:
Given that,
Initial position = 50 m
Final position = 210 m
Time = 5 sec
(a). We need to calculate the average velocity of the car
Using formula of average velocity
[tex]v_{avg}=\dfrac{v_{f}-v_{i}}{t}[/tex]
Put the value into the formula
[tex]v_{avg}=\dfrac{210-50}{5}[/tex]
[tex]v_{avg}=32\ m/s[/tex]
(b). We need to draw the position vs. time graph
We need to calculate the slope of the line of best fit.
Using formula of slop
[tex]slope =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Put the value into the formula
[tex]slope =\dfrac{210-50}{5-0}[/tex]
[tex]slope =32[/tex]
Hence, The average velocity of the car is 32 m/s.
