During the All Stars Skills competition, a puck was launched through the air at a speed of 41 km/h from a height of 2.5 cm. The algebraic model of the path of the puck is defined by h = -4.9t2 + 41t +0.025, where h represents height in cm and t represents time in seconds.

Construct a table of values for the first 10 seconds of the puck’s movement. Round to 0 decimal place?

Using graph paper, graph the data points. Join with a smooth curve. Scan your graph.

c. Approximately how long before the puck will hit the ice? d. For what values of time is the height invalid?
