Wheels are 1.25 inches in diameter
Fastest speed is 3ft/sec
Maximum distance is 16 x (18 cm)
1) How many times does the wheel turn to travel the maximum distance?
1.25 in = 3.175 cm
Circum = pi*d = 3.175pi cm
# of revs = 288/3.175 =~ 90.709
-----------------
2) How long does it take to travel the maximum distance at full speed?
r = 3ft/sec = 91.44 cm/sec
t = d/r = 288/91.443.15 seconds
-------------
3) What is the acceleration needed to travel the maximum distance when starting from a standstill?
Any acceleration > 0 will do.
