Mr Chichester is driving his dark blue camaro to a REO Speedwagon concert. He is driving 15 m/s when he realizes he is going to be late to his favorite band so he slams on the gas for 10s and reaches a final velocity of 45 m/s. How far did Mr. Chichesters travel during this 10s?

300m

Explanation:

step one

given data

initial speed u= 15m/s

final speed v= 45m/s

time taken to attain final speed= 10seconds

Step two:

Let us first solve for the acceleration

a= Δv/t

a= 45-15/10

a=30/10

a= 3m/s

applying the equation of motion

substituting our given data

collect like terms

2025-225=6s

1800=6s

divide both sides by 6

s=1800/6

s=300m

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 !
