Question

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 10.9 s . What are the average acceleration in each interval? Assume that the positive direction is to the right.

Part A

At the beginning of the interval the astronaut is moving toward the right along the x-axis at 14.1 m/s , and at the end of the interval she is moving toward the right at 5.50 m/s .

Part B

At the beginning she is moving toward the left at 5.50 m/s , and at the end she is moving toward the left at 14.1 m/s .

Part C

At the beginning she is moving toward the right at 14.1 m/s , and at the end she is moving toward the left at 14.1 m/s .
