Question

Use Desmos to solve the following problems – I will expect to see screen shots. Part of the challenge is to find a representative window. I will post a few videos to help with this.

3. An object in launched directly upward at 48 feet per second (ft/s) from a platform 160 feet high. The function giving the relationship between height and time is h = -16t2+48t+160. Graph the equation on your calculator and use the graph to answer the following questions. I want to see screen shots and explanations. a. When does the object hit the ground? b. What will be the object's maximum height?

Answer 1

200 150 100 50 0 -50 -100 0 2 3 1 LC st

From graph

when h=0 then t= 5 sec i.e. after 5 sec target hit the ground

also maximum height is about 160 m
