Question

If one object has a greater speed than a second object, does the first necessarily have a greater acceleration? (Answer yes or no) (Have the requested examples ready for class discussion.) Can an object have a northward velocity and a southward acceleration? (Answer yes or no) Have the requested examples ready for class discussion) Can an object be increasing in velocity as its acceleration decreases? (Answer yes or no) (Have the requested examples ready for class discussion.) A sports car accelerates from rest to 27.18m/s in 6.37s. What is the average acceleration? At highway speeds, a particular automobile is capable of an acceleration of about 1.28m/s^2 At this rate, how long does it take to accelerate from 16.25m/s to 32.46m/s? Two locomotives approach each other on parallel tracks. Each has a speed of 4m/s with respect to the ground. If they are initially 8, 998.3m apart, how long will it be before they reach each other?

Explanation / Answer

1)

The acceleration of the object is equal to the ratio of speed and time. So, as the speed of the object increases, acceleration of the object increases.

Answer is ' Yes '.
