**drwls**, Thursday, October 6, 2011 at 12:17amWrite equations for Tom and Dick's locations and solve for the time they are equal. After you have the time, the other two unknowns are easily computed.

X1 = (5/2) t^2 is Tom's location in feet, if t is in seconds. Assume he starts at the origin, X = 0

X2 = 25 - 3 (t-0.21)^2 is Dick's location for t>0.21 s

Solve for t when X1 = X2.

Tom's velocity at that time is 5 t ft/s
