A car traveling at 22 m/s starts to decelerate steadily. It comes to a complete stop in 13 seconds. What is its acceleration?
Anyone?? ):
18m/s 4.25
To find the acceleration of the car, we can use the formula:
acceleration = change in velocity / time
Given that the initial velocity of the car is 22 m/s and it comes to a complete stop in 13 seconds, we can calculate the change in velocity.
Change in velocity = final velocity - initial velocity
Since the car comes to a complete stop, the final velocity is 0 m/s.
Change in velocity = 0 - 22
Now, we can substitute the values into the formula to find the acceleration:
acceleration = change in velocity / time
acceleration = (-22 m/s) / (13 s)
Dividing -22 m/s by 13 s, we can find the acceleration:
acceleration ≈ -1.69 m/s²
Therefore, the car's acceleration is approximately -1.69 m/s². The negative sign indicates deceleration, which means the car is slowing down.
