While traveling along a highway a driver slows from 34 m/s to 17 m/s in 6 seconds. What is the automobiles acceleration?​

-2.83 m/s²

Explanation:

❖ Acceleration is defined as the rate of change in velocity with time.

→ a = (v - u)/t

→ a = (17 - 34)/6 m/s²

→ a = -17/6 m/s²

(Minus sign implies that the velocity is decreasing.)

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
