Question

Suppose you increase your walking speed from 4m/s to 12m/s in a period of 1 s. What is your acceleration?

Answer 1

We use the following formula to determine our acceleration:

`acceleration = ((final velocity) - (initial velocity))/(time) = (change of velocity)/(time)`
We normally use letters in this formula, which gives us:

`a = (v)/(t)`

Filling in this formula gives us:
Δv (change of velocity) = 12 - 4 = 8 m/s
t = 1s

`a = (8)/(1) = 8 m/s^2`
So our answer: the acceleration is
`8m/ s^(2)`
