Multiple Choice

Given $\frac { d ^ { 2 } s } { d t ^ { 2 } } = - 9.8$ , find S if the initial velocity is 10 m/sec upward and the initial position is 5 m above the ground.

• A) \(S = - 4.9 t ^ { 2 } + 10 t + 5\)
• B) \(S = 4.9 t ^ { 2 } + 10 t + 5\)
• C) \(S = - 9.8 t ^ { 2 } + 10 t + 5\)
• D) \(S = 9.8 t ^ { 2 } + 10 t + 5\)
