a train moving at a speed of 15 m/s is accelerated to 45 m/s over a 12 s period. what is the acceleration?

2.5 m/s²

Explanation:

Given:

v₀ = 15 m/s

v = 45 m/s

t = 12 s

Find: a

a = (v − v₀) / t

a = (45 m/s − 15 m/s) / 12 s

a = 2.5 m/s²

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 !
