Question

How much time does it take for a car to come to rest if it has an initial

speed of 22 m/s and slows with an acceleration of -6.1 m/s²?

Answer 1

The car will take 3.6 seconds to come to rest.

Step-by-step explanation:

To find the time it takes for the car to come to rest, we can use the formula:

final velocity = initial velocity + (acceleration × time)

Since the car comes to rest, the final velocity is 0. Therefore, we can rearrange the formula to solve for time: time = (final velocity - initial velocity) / acceleration.

Substituting the given values, we get: time = (0 m/s - 22 m/s) / -6.1 m/s² = 3.6 seconds.
