Initial velocity

$v_i = 60 \, \text{ mph} = 60(\frac{22}{15})$
$v_i = 88 \, \text{ ft/sec}$

${v_f}^2 = {v_i}^2 + 2as$

$0^2 = 88^2 - 2(2)s$

$s = 1936 \, \text{ ft}$ *answer*

SI units

Initial velocity

$v_i = 96.56 \, \text{ kph} = 96.56(\frac{1}{3.6})$
$v_i = 26.82 \, \text{ m/sec}$

${v_f}^2 = {v_i}^2 + 2as$

$0^2 = 26.82^2 - 2(0.61)s$

$s = 589.7 \, \text{ m}$ *answer*
