Answer to Problem 1Q
Circular motion is an example of motion in which the magnitude of the instantaneous velocity is always larger than the average velocity.
Explanation of Solution
Instantaneous velocity is the rate of change of position with respect to time. Whereas the average velocity is the displacement divided by the corresponding time. When an object performs a circular motion, the instantaneous velocity is always greater than the average velocity. This is because the average velocity over any complete cycle is zero since the displacement is zero. But instantaneous velocity assumes some finite value at any given time.
It is obeyed for any object which is accelerating continuously in the direction of velocity.
Conclusion:
Therefore, Circular motion is an example of motion in which the magnitude of the instantaneous velocity is always larger than the average velocity.
(b)
Example of motion having instantaneous velocity is never parallel to the instantaneous acceleration.

Answer to Problem 1Q
In uniform circular motion, the instantaneous velocity is always perpendicular to the instantaneous acceleration.
Explanation of Solution
During uniform circular motion, the object is moving with constant speed, as the object moves in a circle the change in direction is also conatnt.it is an example of motion having instantaneous velocity is never parallel to the instantaneous acceleration.
Conclusion:
Therefore, in uniform circular motion, the instantaneous velocity is always perpendicular to the instantaneous acceleration.

- NASA's KC-135 Reduced Gravity Research aircraft, affectionately known as the "Vomit Comet," is used in training astronauts and testing equipment for microgravity environments. During a typical mission, the aircraft makes approximately 30 to 40 parabolic arcs. During each arc, the aircraft and objects inside it are in free-fall, and passengers float freely in apparent "weightlessness." The figure below shows the altitude of the aircraft during a typical mission. It climbs from 24,000 ft to 30,850 ft, where it begins a parabolic arc with a velocity of 155 m/s at 45.0° nose-high and exits with velocity 155 m/s at 45.0° nose-low. 31 000 45° nose high 45° nose low 24 000 Zero g 65 Maneuver time (s) (a) What is the aircraft's speed (in m/s) at the top of the parabolic arc? 110.0 m/s (b) What is the aircraft's altitude (in ft) at the top of the parabolic arc? 2.04e+04 What is the initial height at the start of the parabolic arc?
