- Passengers on AcTophobia, a free-fall ride at Six Flags over Georgia, sit in cars that are raised to the top of a tower. The cars are then released for 2.6 s of free fall. a) What is their acceleration at the top of the ride (once released)? b) How fast are the passengers moving at the end of this sneeding un nhag16,17A 2-stage rocket is fired from rest. Its acceleration data are shown in the graph below. Plot the v-t and s-t graphs describing the motion of the rocket-clearly showing the shape of the curve (or add a note) and values at inflection points. Show any calculations as well. Then find the velocity of the rocket and its elevation after 20 seconds of flight. a (m/s?) 25 18 (s) 15 20
- Can an object have an acceleration of zero and a velocity that is not zero? Explain why or give an example. Can an object have a velocity of zero and an acceleration that is not zero? Explain why or give an example.26. An object moves along a linear path with constant acceleration. Show mathematically that the average velocity of this object over any interval of time is equal to the instantaneous velocity at a point exactly halfway through that interval of time. Would this be true if the acceleration is not constant?What is the ACCELERATION of an object that is thrown upwards when it reaches the highestpoint?. EXPLAIN.
