Matchbox Car Loop
Rhine
Problem – Constant Velocity Spinning Ride
1. How fast does the wheel
need to spin to make sure
person does not fall from
the top? (VT, , and
RPM)
2. What is person’s apparent
weight at the 12, 3, 6, and
9 o’clock under conditions
above?
3. Repeat problem with
person feeling “1g” at top
of loop.
Use generic r and m for 1-3, then calculate for r = 3m and m = 100 kg
Problem – Matchbox loop
1.
2.
3.
4.
What height does hill need to be to have matchbox car start from rest and have a
“1g” apparent weight at the top of the loop?
For that same situation, find the speed of the car at the 12, 3, 4, 6, and 9 o’clock
positions.
For those same positions, what is the apparent weight of the rider (force you feel
sitting in seat of car)
If car goes though loop once and launches at the 4 o’clock position, find car’s max
height & time, range & time
Use generic r and m to solve problem, then use r = 10m and m = 1000kg to find actual
values. Draw a very large diagram on a separate page, neatly show work.
