Chapter 3, Problem 18E
You’re leading an international effort to save Earth from an asteroid heading toward us at 15 km/s. Your team mounts a rocket on the asteroid and fires it for 10 min, after which the asteroid is moving at 19 km/s at 28° to its original path. In a news conference, what do you report for the magnitude of the acceleration imparted to the asteroid?

The NEXT morning, you wake up in a strange room yet again, and this time you drop a ball from a height of 1.18 m above the floor. The ball hits the floor 0.147 s after your drop it. You guess that you must have been taken to an alien planet with gravity different from Earth s. What is this planet s g (that is, the magnitude of the acceleration due to gravity on this planet)?
In a laboratory test of tolerance for high acceleration, a pilot is swung in a circle 11.5 m in diameter. It is found that the pilot
blacks out when he is spun at 30.6 rpm (rev/min).
At what acceleration (in SI units) does the pilot black out?
Express this acceleration in terms of a multiple of g.
If you want to decrease the acceleration by 13.0% without
changing the diameter of the circle, by what percent must you
change the time for the pilot to make one circle?

You and your team are exploring the edge of an Antarctic mountain range and you send a drone ahead to help navigate. After takeoff you lose sight of the drone and, a few seconds later, the controls malfunction and the drone stops sending visual images and navigational information except for speed and directional data. Changing speeds erratically, the drone heads west until it makes a drastic turn at the 5-minute mark to ß = 45° east of south. After nearly ten minutes, the speed drops to zero and the drone stops sending data. It has crashed. Using the speed/directional data, the team draws up the graph shown below. (a) How far is the drone from you? (b) In what direction must you go to retrieve it?

The astronaut is 12 m from a flat wall and floating toward it at 4 m/s. A ping pong ball bounces back and forth between his paddle and the wall at 11 m/s. Eventually, the astronaut reaches the wall and traps the ball against it. Now treat the “bounce” somewhat realistically. If the bounce lasts 25ms, what is the average acceleration of the ball during this time? Give the magnitude only in m/s^2.arrow_forward
- During your summer internship for an aerospace company, you are asked to design a small research rocket. The rocket is to be launched from rest from the earth's surface and is to reach a maximum height of 980 m above the earth's surface. The rocket's engines give the rocket an upward acceleration so it moves with the acceleration of 16.0 m/s2 during the time T, that they fire. After the engines shut off, the rocket is in free fall. Ignore air resistance. What must be the value of T in order for the rocket to reach the required altitude?arrow_forwardA car drives around a circular track of diameter 161 m at a constant speed of 47.4 m/s. During the time it takes the car to travel 256 degrees around, what is the magnitude of the car s average acceleration? Hint: Do not calculate instantenous accelleration. Instead calculte the average acceleration over the fraction of a complete lap. Average acceleration equals change in velocity divided by change in time, and that this is a two-dimensional situation so you'll have to calculate the x and y components of the average acceleration first and then figure out the magnitude. Remember also that ax = Δvx/Δt and ay = Δvy/Δt. 0 m/s^2 27.91 m/s^2 13.96 m/s^2 9.84 m/s^2arrow_forwardA car travels 90 meters due north in 15 seconds.
