Mississippi Jane is at it again! The big bad evil one has trapped her on an accelerating conveyor belt with a rolling pipe - or so it seems. The pipe is actually not there and instead to be added in during post production for the actress' safety. It is up to you to calculate the proper physics of the pipe so that the CGI pipe may look as realistic as possible. If the pipe is meant to have a mass of 500 (kg) and a mean radius of 0.55 m, determine the pipe's angular acceleration if the conveyor belt has an acceleration of 1.9 Assume the pipe does not slip on the conveyor belt and neglect its thickness. m 8²

After years of asking, you finally were allowed to go on a joy ride in your uncle’s 1956 Mercedes-Benz 300 SL. A notable feature of this vehicle is the gullwing door design that opens from a hinge at the top of the car. Unfortunately, you are having so much fun driving the car that you end up submerged in a fresh water lake. You sink to the bottom of the lake, which has a depth of 10 m. For the sake of simplicity, you can model the door as a 1 m × 1 m square plate, inclined at 45° relative to the floor of the lake. Neglect the weight of the door and friction in the hinge. How much force will be required to open the door, assuming you push from its geometric center?

A child takes a helium balloon on a plane from Denver (with an air pressure of 0.83 atm) on a cool day when the temperature is 20.0oC to Boston (at sea level, with an air pressure of 1.0 atm) where the temperature is 5.0oC.  Assume that no gas escapes from the balloon during the flight.  What is the volume of the balloon in Boston, relative to its size in Denver? Group of answer choices The volume in Boston is 0.79 times the volume in Denver. The volume in Boston is 0.20 times the volume in Denver. The volume in Boston is 0.87 times the volume in Denver The volume in Boston is 1.3 times the volume in Denver. The volume in Boston is the same as the volume in Denver.

The pressure of a car tire depends on the temperature of the air in the tire. While the air temperature is 25 degrees Celsius, the effective pressure is 250 kilo pascals. If the volume of the tire is 0.025 m³, what is the pressure that will occur when the temperature in the tire reaches 50 degrees Celsius?
