Answer:

2m/s²

Explanation:

  • V=Vstart+at
  • rewrite that to find a so a=(V-Vstart)/t

part A of graph

  • a=(20m/s–0m/s)/5s
  • a=4m/s²

part B of graph

  • a=(0m/s–0m/s)/5s
  • a=0m/s²

the average between the two is both answers added divided by the number of answers

  • (4m/s²–0m/s²)/2
  • 4m/s²/2
  • 2m/s²
