Answer: The acceleration of the car is 1.53 m/s². This means that every second, the car's velocity increases by 1.53 meters per second until it reaches 23 m/s after 15 seconds.
Explanation:
The acceleration of the car can be calculated using the formula:
Acceleration (a) = Change in velocity (v) / Time taken (t)
Given that the car starts from rest (initial velocity, u = 0 m/s) and reaches a final velocity (v) of 23 m/s in 15 seconds, we can substitute these values into the formula:
v = v - u
v = 23 m/s - 0 m/s
v = 23 m/s
Now, we can calculate the acceleration:
a = v / t
a = 23 m/s / 15 s
a = 1.53 m/s²
