For a fifth set of maneuvers, the astronaut's partner calculates her average acceleration over the 2 s interval to be -0.7 m/s^2. If the initial velocity of the astronaut was -0.4 m/s, what was her final velocity? Did she speed up or slow down over the 2 s interval?

Step 1
4 \, \text{m/s}\) \(a = -0.7 \, \text{m/s}^2\) \(t = 2 \, \text{s}\) Substitute the values into the formula: \(V_{\text{final}} = -0.4 + (-0.7) \times 2\) \(V_{\text{final}} = -0.4 - 1.4\) \(V_{\text{final}} = -1.8 \, \text{m/s}\) Show more…

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 12 s interval. What is the average acceleration in each interval? Assume that the positive direction is to the right. At the beginning she is moving toward the left at 5.0 m/s , and at the end she is moving toward the left at 14.6 m/s . Express your answer in meters per second squared.

2. An astronaut is piloting her spacecraft toward the International Space Station. To stop the spacecraft, she fires the retro-rockets, which cause the spacecraft to slow down from 20.0 m/s [E] to 0.0 m/s in 12 s. T/I (a) What is the acceleration of the spacecraft? (b) What is the displacement of the spacecraft when it comes to rest?

Launch of the Space Shuttle. At launch the space shuttle weighs 4.5 million pounds. When it is launched from rest, it takes 8.00 $\mathrm{s}$ to reach $161 \mathrm{km} / \mathrm{h},$ and at the end of the first 1.00 $\mathrm{min}$ its speed is 1610 $\mathrm{km} / \mathrm{h}$ . (a) What is the average acceleration (in $\mathrm{m} / \mathrm{s}^{2} )$ of the shuttle (i) during the first 8.00 $\mathrm{s}$ , and (ii) between 8.00 $\mathrm{s}$ and the end of the first 1.00 $\mathrm{min} 7$ (b) Assuming the acceleration is constant during each time interval (but not necessarily the same in both intervals), what distance does the shuttle travel (i) during the first $8.00 \mathrm{s},$ and (ii) during the interval from 8.00 $\mathrm{s}$ to 1.00 $\mathrm{min}$ ?
