Question

A car traveling at 33 m/s starts to decelerate steadily. it comes to a conplete stop in 10 seconds. what is its acceleration?

​

Answer 1

This involves a little handy equation!

First let's mark what is a constant in play here

let iV = initial velocity

let a = acceleration

let eV = ending velocity

• 
  `eV = iV+at`

now that we have our equation we can plug in your numbers.

• 
  `0=33+10a`
• 
  `33=-10a\\`
• 
  `-(33)/(10) = a = -3.3`
