Atruck heading due west increases its speed with a constant acceleration from 12 m/s to 18 m/s in 7.5 seconds. how far does the truck travel during this time? what was the acceleration of the truck during this period?

Explanation:

We can find these answers following the equations of motion.

Δ

Where Δ is the difference between the final speed and the initial speed. And is the time spent

We replace the terms:

We solve the difference:

We divide the terms, so we can have the

2. To find the distance traveled by the truck, we use the equation:

Where is the distance traveled, is the initial speed, is the acceleration and is the time.

We replace the terms:

We multiply and solve the exponential:

Then, we multiply the terms left:

And add, so we can have the

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."
