The position of a car as a function of time is given by x= (50m) + (-5.0 m/s)t + (-10 m/s2)t2(a) What are the initial position, initial velocity, and acceleration of the car? (b) plot x versus t for t=0 to t=2 s (c) What distance does the car travel during the first 1.0 s? (d) What is the average velocity of the car between t=1.0 s and t=2.0 s?

please follow me fast... it's a small request to you

i think they are all correct

explanation:

they seem good

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.
