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... 顯示更多 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 .
最佳解答:
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.
