The distance,
d
, an object travels from rest while accelerating in
t
seconds is given by the formula
d
=
1
2
a
t
2
, where
a
is the acceleration of the object.
Part A: Solve for the acceleration,
a
, to write the equation in terms of the distance,
d
, and time,
t
.
Part B: Solve instead for the time,
t
, and write the equation in terms of the acceleration,
a
, and distance,
d
.
Part C: Explain why it is useful to solve a formula for a specific variable.
