To find the value of t, we need to use the formula: V = V0 + at where: V is the final velocity (55 km/h), V0 is the initial velocity (0 km/h), a is the acceleration (0.5 m/s^2), t is the time (unknown). First, we need to convert the given velocities to m/s: V = 55 km/h = (55 * 1000 m) / (60 * 60 s) ≈ 15.28 m/s V0 = 0 km/h = 0 m/s Now, we can rearrange the formula to solve for t: t = (V - V0) / a t = (15.28 m/s - 0 m/s) / 0.5 m/s^2 t = 15.28 m/s / 0.5 m/s^2 t ≈ 30.56 s Therefore, the value of t is approximately 30.56 seconds.
