(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Plot on a graph the speed-time graph for the Mars lander (Fig 2.2) and find its regression line

This should be y=3.7x+20

This tells you the initial speed was 20 m/s

and the acceleration due to gravity on Mars is 3.7 m/s2

2. Relevant equations

y=mx + b

3. The attempt at a solution

I just need confirmation on my data table:

Time Speed

0 20

1 23.7

2 27.4

3 31.1

4 34.8

5 38.5

6 42.2

7 45.9
