When the car is horizontal, you lift your feet and find that the scale reads 100kg. At another point in the ride, the car is careening down the track with negligible at a slope of 30Degree below the horizontal. What dose the scale read at that point when you lift your feet?

You are riding the new rollercoaster Fizzix Phun at your local amusement park. The technician with a mass of 100kg clears your car for 'takeoff'. The rollercoaster car full of people with a mass of 1000 kg is pulled up the initial hill by a lift device.

Suppose that you bring your car to an auto mechanic. The auto mechanic, to get a better look at what’s broke, puts your car on a hydraulic lift, shown below in which there is an incompressible fluid of density € ρ = 900 kg m3 . A force € F1 is applied to a piston of area € A1 . This supports the weight of the car € F2 on the second piston of area € A2. Assume that both...

You are designing a new roller-coaster. The main feature of this particular design is to be a vertical circular loop-the-loop where riders will feel like they are being squished into their seats even when they are in fact upside-down (at the top of the loop). The coaster start at rest a height of 80m above the ground, speeds up as it descends to ground level, and then enters the loop which has a radius of 20m. Suppose a rider is...

1. A roller coaster has a 300 kg car. Assume the track is frictionless. a) The car starts at a speed 20 m/s on a horizontal track. It then goes through a circular loop. What is the speed of the car when it is at the top of the loop, h = 10 m above the horizontal track? b) What is the normal force applied from the track at the point? Does this force point upward or downward? Assume the...
