Question

A graph titled velocity versus time has horizontal axis time (seconds) and vertical axis velocity (meters per second). A line has 5 straight segments. Line segment A runs from 0 seconds 0 meters per second to 1 seconds 30 meters per second. Then segment B runs to 3 seconds 30 meters per second. Then an unlabeled segment runs to 4 seconds 40 meters per second. Then an unlabeled segment runs to 5 seconds 40 meters per second. Then segment C runs to 6 seconds 10 meters per second. Then segment D runs to 7 seconds 10 meters per second. Then an unlabeled segment runs to 8 seconds 40 meters per second. Then an unlabeled segment runs to 9 seconds 40 meters per second. Then segment E runs to 10 seconds 20 meters per second. What is the acceleration of the car at segment C? 30 m/s2 –30 m/s2 40 m/s2 –40 m/s2.

Answer 1

Answer:

-30m/s

Step-by-step explanation:

Acceleration is the change in velocity with respect to the time. The acceleration of the car at segment C is -30 meter per second squared. Hence the option B is the correct option.

Given information-

Segment A runs from 0 seconds 0 meters per second to 1 seconds 30 meters per second.

Segment B runs to 3 seconds 30 meters per second.

Segment C runs to 6 seconds 10 meters per second.

Segment D runs to 7 seconds 10 meters per second.

Segment E runs to 10 seconds 20 meters per second.

Acceleration

Acceleration is the change in velocity with respect to the time. Acceleration of a vector quantity which means it has both magnitude and the direction. It can be given as,

Here  denotes the time and  denotes the velocity of the body.

Acceleration at segment C,

Thus the acceleration of the car at segment C is -30 meter per second squared. Hence the option B is the correct option.

Answer 2

Acceleration is the change in velocity with respect to the time. The acceleration of the car at segment C is -30 meter per second squared. Hence the option B is the correct option.

Given information-

Segment A runs from 0 seconds 0 meters per second to 1 seconds 30 meters per second.

Segment B runs to 3 seconds 30 meters per second.

Segment C runs to 6 seconds 10 meters per second.

Segment D runs to 7 seconds 10 meters per second.

Segment E runs to 10 seconds 20 meters per second.

Acceleration

Acceleration is the change in velocity with respect to the time. Acceleration of a vector quantity which means it has both magnitude and the direction. It can be given as,

$a=\dfrac{\Delta v}{\Delta t}$

Here $t$ denotes the time and $v$ denotes the velocity of the body.

Acceleration at segment C,

$a_c=\dfrac{10-40}{6-5}$

$a_c=-30$

Thus the acceleration of the car at segment C is -30 meter per second squared. Hence the option B is the correct option.
