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
[tex]a=\frac{vf-vi}{t}[/tex]we substitute the information
[tex]a=\frac{60\text{mph}-0\text{mph}}{2.8\sec }=\frac{60\text{mph}}{2.8\text{ sec}}=21.43\text{ mph/sec}[/tex]The acceleration of the Tesla is 21.43 mph/sec
