Question

TA penny is dropped from a height of

Answer 1

The penny reaches the water at 3.5 seconds

The height function is given as:

$d = -16t^2 + 196$

(a) Graph the function

See attachment for the graph of the function

(b) Time to reach the water

From the graph, the curve of $d = -16t^2 + 196$ crosses the x-axis at points t = -3.5 and t = 3.5

But the time (t) cannot be negative.

Hence, the penny reaches the water at 3.5 seconds
