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

question 49

Multiple Choice

An object moving vertically is at the given heights at the specified times.Find the position equation $s = \frac { 1 } { 2 } a t ^ { 2 } + v _ { 0 } t + s _ { 0 }$ for the object. At t = 1 second,s = 299 feet
At t = 2 seconds,s = 281 feet
At t = 3 seconds,s = 231 feet

• A)? \(s = - 16 t ^ { 2 } - 30 t + 299\)
• B)? \(s = - 16 t ^ { 2 } - 30 t - 285\)
• C)? \(s = - 32 t ^ { 2 } + 30 t + 299\)
• D)? \(s = - 16 t ^ { 2 } + 30 t + 285\)
• E)? \(s = - 8 t ^ { 2 } + 2 t - 285\)
