Textbook Question
Chapter 3, Problem 18SEQ
Explain all answer clearly, with complete sentences and proper essay structure if needed. An asterisk (*) designates a quantitative problem, for which you should show all your work.
What Makes It Science? Choose one idea from the modern view of the cosmos as discussed in Chapter 1 (such as “The universe is expanding” or “We are made from elements manufactured by stars”.)
- Describe how this idea reflects each of the three hallmarks of science, discussing how it is based on observations, how our understanding of it depends on a model, and how that model is testable.
- Describe a hypothetical observation that, if it were actually made, might cause us to call the idea into question. Then briefly discuss whether you think that, overall, the idea is likely or unlikely to hold up to future observations.

1. 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. The downward negative pull on the object is represented by
Solve for t.

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).
