Question:
Which of the following accelerations is the smallest in magnitude (ignore positive or negative signs)?
A.)Not enough information
B.)acceleration from 0 to 30 m/s in 2 s
C.)deceleration from 30 m/s to 10 m/s in 1.5 s
D.)gravity on Earth
The gravity on the Earth has acceleration is smallest in magnitude Given:Acceleration from 0 to 30 m/s in 2 sDeceleration from 30 m/s to 10 m/s in 1.5 sGravity on EarthTo find:The accelerations with the smallest magnitude Solution:Acceleration from 0 to 30 m/s in 2 s
The acceleration in 2 seconds:[tex]=\frac{30 m/s-0 m/s}{2s}=15 m/s^2[/tex]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:[tex]=\frac{10m/s-30 m/s}{1.5 s}=-13.4 m/s^2[/tex]The magnitude of the deceleration is 13.4.Gravity on earthThe value of the acceleration due to gravity = [tex]g = 9.8 m/s^2[/tex]The magnitude of the acceleration is 9.8.9.8 < 13.4 < 15The gravity on the Earth has acceleration is smallest in magnitude.Learn more about the acceleration here:brainly.com/question/2437624?referrer=searchResultsbrainly.com/question/7488209?referrer=searchResults
