You are traveling in a car that is moving at a velocity of 30 m/s. Suddenly, a car 15 meters in front of you slams on its brakes. At that moment, you also slam on your brakes and slow to 10 m/s. Calculate the acceleration if it took 3 seconds to slow your car down.

The acceleration of car is 6.67 m/s².

Explanation:

Given that,

Initial velocity = 30 m/s

Distance = 15 m

Final velocity = 10 m/s

Time = 3 sec

We need to calculate the acceleration

Using formula of acceleration

Negative sign shows the car is slowing down.

Hence, The acceleration of car is 6.67 m/s².

depends on what you mean by "group." for order, it would be coleoptera (beetles). for class, it would be insecta (insects). for phylum, it would be the arthropoda (animals with jointed exoskeletons).

explanation:

there are no components of a physical goal mentioned on the list of choices that you've provided.
