<PRE><B>Question 465333</B>
The range of a projectile is directly proportional to the square of its velocity. If a motorcyclist can make a jump of 237.2 feet by coming off a ramp at 79mph, find the distance the motorcylist could expect to jump if the speed coming off the ramp were increased to 84mph. Round to the nearist tenth of a foot.
--------------
{{{s = kv^2}}}
{{{237.2 = k*79^2 = 6241k}}}
k = 237.2/6241
---------------
d = k*84^2 = 7056k
d = 237.2*7056/6241
d =~ 268.2 feet
