question 57

Multiple Choice

Use the position equation $s = - 20 t ^ { 2 } + v _ { 0 } t + s _ { 0 }$ , where $S$ represents the height of an object (in feet) , $\mathcal { V } _ { 0 }$ represents the initial velocity of the object (in feet per second) , $s _ { 0 }$ represents the Initial height of the object (in feet) , and $t$ represents the time (in seconds) .

• A) \(t = 13 \mathrm { Sec }\)
• B) \(t = 12 \mathrm { Sec }\)
• C) \(t = 20 \mathrm { Sec }\)
• D) \(t = 11 \mathrm { Sec }\)
• E) \(t = 10 \mathrm { Sec }\)
