Question

Look at the equation. What detail is missing? 3 m/s2= (33 m/s - X)/30 S
​

Answer 1

The starting velocity.

Step-by-step explanation:

We must understand that this equation comes from the following equation of kinematics.

`v_(f)=v_(o)+a*t`

where:

Vf = final velocity = 33 [m/s]

Vo = starting velocity [m/s]

a = acceleration = 3 [m/s²]

t = time = 30 [s]

So, these values can be assembly in the following way:

`v_(f)=v_(o)+a*t\\a*t=v_(f)-v_(o)\\3=(33-v_(o))/(30)`
