Answer :
So the cars change is speed is 35m/s (45m/s - 10m/s) and has taken 4s to do so.
acceleration is measured in m/s^2 or (m/s)/s,
to calculate the acceleration = change is speed / time take in this case:
35/4 = 8.75m/s^2
acceleration is measured in m/s^2 or (m/s)/s,
to calculate the acceleration = change is speed / time take in this case:
35/4 = 8.75m/s^2
