Module 2 - Discussion: Find It!

Find & Post

The distance s (in m) above the ground for a projectile fired vertically upward with a velocity of 4[ a ] m / s as a function of time t (in s ) is given bys = 4 [ a ] t − 4. [ b ] t 2.

Your instructor will provide you with a and b.

Find the answers to these questions.

• find t for v = 0
• find v for t = 4
• find v for t = 5
• What conclusions can you draw?

State the values you are using for a and b before you show the work to answer these four questions. Remember to use the Canvas Equation Editor. Refer to the Tools for Mathematics page in the Course Specific Information module for technical guidance. Post your answers in the discussion area by the fourth day of the module week.

Review & Discuss 

Compare and contrast your work to that of your classmates. Engage in a dialogue, addressing one or more of the following areas: 

• Do you agree with the work and explanations?
• Where are the errors in the proposed solutions (mine or classmates')?
• Which solution is correct? Why? Is there more than one way to get to the correct solution?
• Are some of the explanations clearer than others? What makes them easier to understand?
• Do you have suggestions for improvement?
• Have we each given thorough explanations for our work?
• Which way is easier?
