Question

What is the acceleration of an object going from O m/s to 25 m/s in 5s?

Answer 1

5m/s^2 is the acceleration.

Answer 2

`\boxed {\boxed {\sf a= 5 \ m/s^2}}`

Step-by-step explanation:

Acceleration is the change in speed over time.

`a=( v_f-v_i)/(t)`

The object accelerates from 0 meters per second to 25 meters per second in 5 seconds.

`v_f= 25 \ m/s\\v_i= 0 \ m/s \\t= 5 \ s`

Substitute the values into the formula.

`a=( 25 \ m/s -0 m/s )/( 5 \ s)`

Solve the numerator.

`a=(25 \ m/s)/(5 \ s)`

Divide

`a= 5 \ m/s/s= 5 \ m/s^2`

The object's acceleration is 5 meters per square second.
