An object is propelled off of a platform that is 75 feet high at a speed of 45 feet per second (ft./s). The height of the object off the ground is given by the formula h(t) = - 16t+45t+75, where h(t) is the object's height at time (t) seconds after the -16 object is propelled.

Be sure to apply a model from this class and include the relevant diagram(s) for that model. And don’t forget to use the Claim, Evidence, Reasoning framework to present your solution. Phenomenon: Runaway Truck Ramp A truck was driving on a highway at 30 m/s when its brakes gave out. The driver steered it onto a “runaway truck ramp”, consisting of an upward ramp (rising 12 meters vertically over 120 meters horizontally), and ending with a compressible barrier which you can model as a giant spring with spring constant “k”. The compressible barrier can be compressed by a maximum 0.5 meters before it stops working. Graphic attached Values: Mass of the truck: 20 metric tons (1 metric ton = 1000kg). Mass of the driver: Choose a reasonable value. Truck Ramp Dimensions: 12 meters vertical, 120 meters horizontal Spring constant k= 6.0 x 107 J/m2. Part 1: Big…arrow_forward

The method has proven invaluable for providing calendar dates for a range of different materials and many different time periods. Radiocarbon dating, however, is not without its limitations and uncertainties, so it is important for archaeologists to be aware of a range of issues when using the technique. For the second part of this assignment, please answer the questions below. 6. List two kinds of archaeological materials can be dated using the radiocarbon method and two that cannot be dated with radiocarbon. 7. In one or two sentences, explain why radiocarbon ages need to be calibrated into calendrical ages? 8. A radiocarbon date on wood charcoal was obtained from Layer N in the stratigraphic profile above. The date has a radiocarbon age of 5500 BP ± 50 yrs and it calibrates to 4450-4260 cal. BC.
