Question

4. What is the acceleration of a car that is going 50 m/s north and remains at that constant speed and direction for 10 seconds?1) 0.0 m/s/s2) 5 m/s/s3) - 5 m/s/s4) Not enough information

Answer 1

acceleration = change of speed / time

a = Δv / t

Since the speed remains constant, acceleration is zero.

1) 0.0 m/s
