11. A Speeding Car Given: Initial velocity = 15 m/s, final velocity = 27 m/s, time = 4 s. Acceleration is the change in velocity divided by the time: a = (vf − vi) / t a = (27 − 15) / 4 = 12 / 4 = 3 m/s2 Answer: The car’s acceleration is 3 m/s2. 12. An Accelerating Sled Given: Initial velocity = 0 m/s (starts from rest), acceleration = 2.5 m/s2, time = 6 s. For constant acceleration, final velocity is calculated using: vf = vi + at vf = 0 + (2.5 × 6) = 15 m/s Answer: The sled’s final velocity is 15 m/s.
