Let’s check out your problem:

To score a field goal in football, a player kicks the ball up into the air with an initial upward velocity of $56$ feet per second. Therefore, the football's height above the ground in feet, $t$ seconds after it is kicked, can be modeled by the expression $-16t^2 + 56t$. This expression can be written in factored form as $-16t(t - 3.5)$.$\newline$What does the number $3.5$ represent in the expression?$\newline$Choices:$\newline$(A)the height in feet of the football when the player kicks it$\newline$(B)the time in seconds from when the player kicks the football until it lands on the ground$\newline$(C)the height in feet of the football when it reaches its highest point$\newline$(D)the time in seconds from when the player kicks the football until it reaches its highest point
