Answer:
B. 3.75 meters/second2
Explanation:
The velocity of a car traveling in a straight line increases from 0 meters/second to 30 meters/second in 8 seconds. What is the average acceleration of the car;
acceleration = (change in velocity)/(change in time)
acceleration = ( 30 - 0)/(8)
acceleration = 3.75 meters/second2
Answer: b
Explanation:
I could be wrong but because it’s at zero it can be calculated
The <em><u>gravity on the Earth</u></em> has acceleration is smallest in magnitude
Given:
- Acceleration from 0 to 30 m/s in 2 s
- Deceleration from 30 m/s to 10 m/s in 1.5 s
- Gravity on Earth
To find:
The accelerations with the smallest magnitude
Solution:
- Acceleration from 0 to 30 m/s in 2 s
The acceleration in 2 seconds:
The magnitude of the acceleration is 15.
- Deceleration from 30 m/s to 10 m/s in 1.5 s
The deceleration in 1.5 seconds:
The magnitude of the deceleration is 13.4.
The value of the acceleration due to gravity =
The magnitude of the acceleration is 9.8.
9.8 < 13.4 < 15
The <em><u>gravity on the Earth</u></em> has acceleration is smallest in magnitude.
