Question

I really need help on this. *my teachers is gruesome-

1. A car starts out at 0 meters per second. It ends up at 100 meters per second . The time is 20 seconds. Calculate acceleration
2.A roadrunner accelerates for 20 meters per second to 60 meters per second in 5 seconds.
3.A lizard running from the roadrunner gets squashed by the car. It was running at 30 meters per second when it got squashed. It’s final velocity is now 0 meters per second because it’s road kill...The time was 10 seconds.

Answer 1

Wait I don't see the question... Can you comment me in it so I can see? I think it's a glitch or something..
