Chapter 6, Problem 9P
The Indy 500. The Indianapolis Speedway (home of the Indy 500) consists of a 2.5 mile track having four turns, each 0.25 mile long and banked at 9°12′. What is the no-friction-needed speed (in m/s and mph) for these turns? (Do you think drivers actually take the turns at that speed?)

1. I am driving my 3500 pound weight car at 45 mph around a flat curve of radius 50 meters. If the us = 0.85,
do I make it around the curve?
(Y/N). It starts raining and the us drops to .65. Do I make it now?
(Y/N). At that speed what is the kinetic energy of my car?

2. Tom is doing a bucket lab with a mass of 5 kg of water. If he swings it 8 times around in 8 seconds and his
arm is 0.8 meters long, what centripetal force is the bucket putting on his shoulder?
Does the water fall on him?
Newtons.
_(Y/N). If he were on Mars (m-6.42*10^23 Kg, R=3397000 meters)
would he get wet?
3. You are working on a pumped storage facility design. You have a pond on top of a hill. You approximate the
pond as a cylinder with a diameter of 1500 feet and an average depth of 20 feet. The center of the pond is 300
feet above a river where you will let the pond full of water flow thru a turbine making electricity. What is the
GPE of the pond?

1.Circular Motion: Your evil cousin Throckmorton has come to visit for the weekend. His favourite pastime is skateboarding. You observe him skateboard from rest down a curved, frictionless ramp. If we treat Throckmorton and his skateboard as a particle, he moves through a quarter circle with radius 3.00m. Throcky and his skateboard have a mass 25.0kg. (a) Find his speed at the bottom of the ramp.(b) Find the normal force that acts on him at the bottom of the curve.
7. A car travels at a constant speed around a circular track whose radius is 2.6 km. The car
