- box the finals answers. Provide the necessary explanations for your solutions. Show the necessary diagrams.arrow_forwardAnswer Activity in a separate paper. Show the solution for every answer (for problem solving ones only). In presenting solution, it should be in the same sequence as the asked problem. Avoid too many erasures (to prevent this, solve first in a scratch paper and after finalizing, transfer it to the final paper for submission). Box your final answer with appropriate units. Retain 3 decimal places for intermediate value calculation. Not following instruction means a corresponding point deduction. 1.

Explain in two to three sentences what the meaning of the solution(s) are in relation to the problem situation. A rubric has been provided for reference. 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.arrow_forwardExplain your reasoning.arrow_forwardComplete the questions below using additional paper if needed. This is a closed-note, closed-book exam. All equations and required information will be provided to you. To receive credit, all work must be shown. Partial credit is given generously for any form of attempt, but blank answers and answers with no work get no points.
