What is the acceleration of a car moving along a straight road that increases its speed from 0 to 100 km/h in 10 s?
To find the acceleration of the car, we first need to convert the speed from km/h to m/s.
1 km/h is equal to 1000 m/3600 s = 0.27778 m/s
So, 100 km/h is equal to 100 x 0.27778 m/s = 27.78 m/s
Acceleration (a) can be calculated using the formula:
a = (final velocity - initial velocity) / time
a = (27.78 m/s - 0 m/s) / 10 s
a = 2.778 m/s^2
Therefore, the acceleration of the car is 2.778 m/s^2.
