question 97

Multiple Choice

A free-falling object is described by $h = 35 t + \frac { 1 } { 2 } a t ^ { 2 }$ , where h is the height above the ground, t is the amount of time the object is falling, and a is the acceleration. Solve the equation for a .

• A) \(a = \frac { 2 ( h - 35 t ) } { t }\)
• B) \(a = \frac { 2 ( h + 35 t ) } { t ^ { 2 } }\)
• C) \(a = \frac { 2 ( h - 35 t ) } { t ^ { 2 } }\)
• D) \(a = \frac { h - 35 t } { t ^ { 2 } }\)
• E) \(a = \frac { h - 35 t } { 2 t ^ { 2 } }\)
