Question

What is the acceleration of a Tesla that accelerates from 0-60 mph in 2.8 seconds.Give your answer in mph/sec.

Answer 1

We have the next information

vi= initial velocity

vf- final velocity

a= acceleration

t=time

in our case

vi=0 mph

vf=60 mph

a=?

t=2.8 sec

we will use the next formula

`a=(vf-vi)/(t)`

we substitute the information

`a=\frac{60\text{mph}-0\text{mph}}{2.8\sec }=\frac{60\text{mph}}{2.8\text{ sec}}=21.43\text{ mph/sec}`

The acceleration of the Tesla is 21.43 mph/sec
