Question

A velocity-time graph is shown below: (2 points)

What is the average acceleration of the object represented in the graph above over the 10 seconds?
0 m/s2
2 m/s2
4 m/s2
6 m/s2

Answer 1

constant

Step-by-step explanation:

b/c it is right (going forward at a constant rate)

Answer 2

2m/s²

Step-by-step 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
