Dominic Toretto is angry that you insulted his family. He quickly steps on his gas pedal, making his 1970 Dodge Challenger go from a stopped position to 75 km/h in 6.5 seconds.
a. What is his acceleration in meters per second squared (m/s2)?
b. If he brakes suddenly bring the car from 75 km/h to an abrupt stop in 4.5 seconds what would his acceleration be?
