The first part is pretty straight forward, vₓ=v₀+a (t). Convert final velocity to m/s to get 97.2m/s. v₀=0, a=4. Solving for t yields 24.3 seconds.

For the second part use "vₓ^2 (final velocity) = v₀^2 (initial velocity) + 2a (Δx). Final velocity is 97.2m/s, initial velocity is 0, acceleration is 4m/s^2. Solving for Δx yields 1181.53 meters.
