The table shows test data for a corvette, one of the fastest cars made in the us. the car is moving in a straight line (the x- . time (s) 0/2.10/20.0/53.0. speed (mi/h)0/60.0/210/255. 1. calculate the car's average acceleration (in m/s2) between 2.1 s and 20.0 s.. 2. calculate the car's average acceleration (in m/s2) between 20.0 s and 53 s.

Answer

part 1) 3.746 m/s²

Part 2) 0.6096 m/s²

Explanation

Acceleration is the rate of change of speed.

It is calculated as follows:

Acceleration = Change in speed/change in time

a = (v - u)/t

Part 1

1mi/h = 0.44704 m/s

60 mi/h = 60 × 0.44704

= 26.8224 m/s

210 mi/h = 210 × 0.44704

= 93.8784 m/s

a = (93.8784 -26.8224 )/(20 - 2.1)

= 67.056/17.9

= 3.746 m/s

Part 2

1mi/h = 0.44704 m/s

255 mi/h = 255 × 0.44704

= 113.995 m/s

a = (113.995 - 93.8784)/(53 - 20)

=20.1166/33

= 0.6096 m/s²

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.
