Question 904055: An automobile traveling on a straight, level road at 50km/h in 30s. What was the magnitude of the auto's acceleration in m/s^2
Answer by brysca(112) (Show Source): You can put this solution on YOUR website!
Acceleration measures the change of an object's velocity. In the problem, the car's velocity remains at 50km/hr from
the beginning to the end of the 30 seconds. Since there is no change of velocity, there is no acceleration. a=0.
I have attached work explaining the solution below.
