The position of a ball at time t is specified by the point (x(t), y(t)) where x(t) = 20t and y(t) = 40t – 10t2 . If distance is measured in meters and time is in seconds, Homework Help ✎
When will the ball land?
How far does the ball travel horizontally?
How high does the ball go?
This occurs when y(t) = 0.
Use your answer from part (a) to evaluate x(t).
If you graph only y(t), what is the shape of the graph? Where does the max occur on this type of graph?
