The driver of a sports car traveling at 10.0⁣m/s steps down hard on the accelerator for 5.0⁣s and the velocity increases to 30.0⁣m/s. what was the average acceleration of the car during the 5.0s time interval?

Explanation:

From the concept of average acceleration we know that

From the exercise we know that

So, the average acceleration of the car is:

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
