An Object Moving Vertically Is at the Given Heights at the Specified

question 45

Multiple Choice

An object moving vertically is at the given heights at the specified times. Find the position equation $s = \frac { 1 } { 2 } a t ^ { 2 } + v _ { o } t + s _ { o }$ for the object.
At $t = 1$ second, $s = 198$ feet
At $t = 2$ seconds, $s = 182$ feet
At $t = 3$ seconds, $s = 134$ feet

• A) \(s = - 32 t ^ { 2 } + 32 t + 198\)
• B) \(s = - 16 t ^ { 2 } + 32 t - 182\)
• C) \(s = - 16 t ^ { 2 } + 32 t + 182\)
• D) \(s = - 8 t ^ { 2 } + 2 t - 182\)
• E) \(s = - 16 t ^ { 2 } - 32 t + 198\)
