Question

1. What is the acceleration of a car going from 0-70 in 10 seconds?

Answer 1

Acceleration = (70-0)/10 = 7 m/s^2

Answer 2

Answer:

a = 1.944 m/s^2

Given, Initial velocity 'u' = 0

Final Velocity 'v' = 70 km/h = 19.44m/s

Time 't' = 10 seconds

Explanation:

Acceleration = (Final Velocity-Initial Velocity)/Time

=> a = (v-u) / t

=> a = (19.44-0)m/s / 10s

=> a = 19.44 / 10 m/s^2

=> a = 1.944 m/s^2
