A car is traveling up route 8 at 50 mph when he hits the gas and increases his speed 80 mph in 3 seconds. What is his acceleration in this time frame?

10m/s²

Explanation:

using a=(v-u)/t. where a is acceleration, v is final velocity, u is initial velocity and t is time

v is 80 mph, u is 50 mph, t is 3s, a is ?

a=(80-50)/3

a=30/3

a=10m/s²

i would think it's food chain

thermal energy is the answer
