Answer:
The difference in velocity divided by rate = acceleration.
80 - 10 = 70km/h
60 sec. per hour, so 70 × 60 = 4,200 km/s
4.200/8=525
520/60 = 8.6666666667 km/h
Explanation:
Not the answer but hope it puts you in the neighborhood.
The resultant acceleration of the car is 2.43 m/s².
Acceleration is define as the rate of change of velocity with respect to the time and it will be calculated as:
Acceleration = Velocity / Time
Given that, velocity of car = 80km/h - 10km/h = 70km/h
As we know that 1 km = 1000m
and 1 hour = 3600 sec
So that 70km/h = 19.4 m/s
Given time = 8 sec
Now putting values on the acceleration equation, we get
Acceleration = 19.4 m/sec / 8sec = 2.43 m/s²
Hence required acceleration is 2.43 m/s².
