Chapter 2: Q8. (page 41)

Can an object be increasing in speed as its acceleration decreases? If so, give an example. If not, explain.

Short Answer

Expert verified

Yes, an object is increasing in speed as its acceleration decreases.

Step by step solution

01

Step 1. Meaning of acceleration

Acceleration can be defined as the rate of change of velocity of an object. It is a vector quantity since it has both direction and magnitude.

02

Step 2. Citing an example explaining that an object is increasing in speed as its acceleration decreases

Assume the north to be the positive direction. If a car is going south and gaining speed at an increasing rate, the magnitude of its acceleration is large. However, since the acceleration is directed southward, it becomes increasingly negative.

In other words, the acceleration of the car decreases as its speed increases.

A car slows down from 28 m/s to rest at a distance of 88 m. What is its acceleration, assumed constant?

A car is behind a truck going18m/son the highway. The car鈥檚 driver looks for an opportunity to pass, guessing that his car can accelerate at0.60m/s2and that he has to cover the 20-m length of the truck, plus 10-m extra space at the rear of the truck and 10 m more at the front of it. In the oncoming lane, he sees a car approaching, probably at the speed limit,25m/s(55 mph). He estimates that the car is about 500 m away. Should he attempt the pass? Give details.

If one object has a greater speed than a second object, does the first necessarily have a greater acceleration? Explain, using examples.

Which of these motions is not at constant acceleration: a rock falling from a cliff, an elevator moving from the second floor to the fifth floor making stops along the way, a dish resting on the table? Explain your answers.
