Answer:

a) 41m/s

Explanation:

Answer:

a 41

Explanation:  

First, calculate the distance traveled in the first two seconds using the graph. The starting distance is 100 m. The distance at the two second mark is about 18 m. 100 - 18 = 82 m. Next use the speed formula, v = d/t to calculate the average speed: 82m/2s = 41m/s.
