    Eqn: d = 1/2 ( Vf + Vi ) × t

    As long as acceleration (or decceleration) is constant.

    There is insufficient data to answer this question. For one thing, the value for acceleration isn't given, which is an absolute requirement. An object that is "shot" is assumed to have started from a velocity of 0, so what was the initial acceleration used to achieve the 29 m/s value?

    Second, there is no launch angle given (I suppose we could assume 90° perpendicular to Earth's surface), and this is also required.

    Finally, the "place" of the launch is not mentioned. If this is in Earth's atmosphere, from sea level, then that's one thing. But if it were shot from the Moon, or from the floor of the ocean, then the values would be completely different.
