3. A runner has constant acceleration for 6.4 seconds over a 20 m distance starting from rest. What is the acceleration of the runner?
a.
b. If it takes the runner 6.4 s to run the 20 m distance, what is the runner's final velocity?

You need to use the equations of motion which I wrote down in the image. Since the runner starts from rest, the initial velocity(v0) is 0 and initial position(x0) is also 0. The solution is in the image attached below.

3.2x10^7

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !
