Question

Which object is not accelerating?

Group of answer choices

A ladybug crawling forward at constant rate of 2.5 m/s.

A blue Ford 150 pick-up truck speeding up from 50 mph to 80 mph.

A baseball player sliding into home base.

A student riding on a Ferris wheel at a constant rate of 5.0 m/s.

Answer 1

I believe the correct answer would be A.) A ladybug crawling forward at a constant rate of 2.5 m/s.

Step-by-step explanation:

Acceleration is based on movement in three different ways: speeding up, slowing down, and changing direction.

For choice A, the ladybug is moving in one direction, at a constant rate. IT isn't speeding up, nor slowing down. It is going in one direction, therefore it is not accelerating.

In choice B, the Ford is speeding up, therefore, that is considered acceleration. The baseball player is slowing down. That is also classified as acceleration. In answer choice D, the student is changing direction by going in a circle. Therefore, the only answer that makes sense is choice A.

Hope this helps,

Answer 2

Answer: Option A "A ladybug crawling forward at constant rate of 2.5 m/s."

Explanation: Acceleration is defined as the rate of change of the velocity.

This means that if a given object has no acceleration, there is no change in the velocity of the object.

For example, in the second option "

A blue Ford 150 pick-up truck speeding up from 50 mph to 80 mph." there is a change in the magnitude of velocity, so the car is accelerating.

In the third option "A baseball player sliding into home base." The player is sliding, then he is experiencing friction force, wich stopping him, so he is experiencing acceleration.

The fourth option "A student riding on a Ferris wheel at a constant rate of 5.0 m/s." Here you can see that the velocity is constant, so you may think that there is no acceleration involved here, but is not the case, the student is in a Ferris wheel, so his movement is in a circle, this means that the direction in which the velocity is applied changes all the time (at some point is pointing down, at other point is pointing up) this means that the velocity is changing, so there is acceleration (in this case is called centripetal acceleration)

Then, the right option is the first one, because is moving "forward" (direction does not change) and at a costant rate (magnitude of velocity does not change)
