A car travels in a straight line for 4.8 h at a
constant speed of 63 km/h .
What is its acceleration?
Answer in units of m/s
2
constant speed? acceleration is zero.
To find the acceleration of the car, we need to use the formula for acceleration:
Acceleration = Change in velocity / Time
Since the car is travelling at a constant speed, the change in velocity is zero. Therefore, the acceleration of the car is also zero.
In units of m/s^2, the acceleration is written as 0 m/s^2.
