Chapter 4, Problem 14SEQ
Explain all answers clearly, with complete sentences and proper essay structure, if needed. An asterisk (*) designates a quantitative problem, for which you should show all your work.
Patters of Motion. In one or two paragraphs, summarize the orderly patterns of motion in our system and explain why they suggest that the Sun and the planets all formed at one time from one cloud of gas, rather than as individual objects at different times.

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.

- Instructions: Your task is to create a model in response to the prompts in the question below. 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_forwardB.
