A tennis ball is dropped from a height of $16$ feet. It’s height (in feet) above the ground can be modeled by the piecewise function $$H(t) = \left\{ \begin{array}{ll} 16(1 - t^2) \amp 0 \leq t \leq 1 \\ (4 - 4t)(4t - 10) \amp 1 \lt t \leq 2.5 \\ \end{array} \right.$$ where $t$ is measured in seconds after it was dropped.

1. What is $H(1)\text{?}$
   Answer: ? feet seconds
2. What is $H(2)\text{?}$
   Answer: ? feet seconds
