#1/3 "mi/s"^2#

Since #v=u+at#, where #v# is the final velocity, #u# the initial velocity, #a# the acceleration and #t# the time we can solve the above.

Here, #u=0 \ "mi/hr"#. So the equation reduces to:

#v=at#

Rearranging to solve for #a#:

#a=v/t#

Which is the actual equation for acceleration.

Here, #t=3 \ "s"# and #v=1 \ "mi/s"#, so we have:

#a=1/3 "mi/s"^2#
