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
