Question
KNe ealoulation gave us the change in velocity during the given time interval To eulate the final velooity, we need to use the definition of change in velocity Av VV Substituting the values in the equation, we get V-20n/s 24m/s V 44m/s Therefore, the final velooity of the racer is 44 m/s, What's More Activity 3.8: Through the Graph!
