An astronaut has left the International Space Station to test a new space scooter. Her partner measures the following velocity changes, each taking place in a time
interval 11.4s . What are the average acceleration in each interval? Assume that
the positive direction is to the right.
At the beginning she is moving toward the right at 14.0 m/s , and at the end she is moving toward the left at 14.0 m/s .

✔ 最佳答案
Average acceleration = change in velocity/time interval= (-14 - 14)/11.4 m/s^2 = -2.46 m/s^2
The acceleration is 2.46 m/s^2 in direction towards the left.
