Final answer:
To determine the magnitude of the UFO's acceleration and its final speed, you can use the equation v = v₁ + at. Given the initial velocity, time, and change in velocity, you can calculate the acceleration. The final speed can be found by adding the change in velocity to the initial velocity.
Step-by-step explanation:
The magnitude of the acceleration of the UFO can be determined using the equation v = v₁ + at, where v is the final velocity, v₁ is the initial velocity, a is the acceleration, and t is the time. To find the final speed of the UFO, you will need to know its initial velocity, acceleration, and time.
- Identify the knowns: vo = 30.0 km/h, t = 0 s (assuming the UFO starts from rest).
- Solve for the change in velocity, Av: Av = Uf - Vo. In this case, Av = 0 - 30.0 km/h = -30.0 km/h.
- Plug in the knowns, Av and t, and solve for a: a = Av / t = (-30.0 km/h) / (0 s) = 0 km/h/s.
The magnitude of the UFO's acceleration is 0 km/h/s and the final speed of the UFO is 30.0 km/h.
