WebSep 17, 2024 · 1) A speedboat has an acceleration of 2 m/s2. What would the final velocity of the speedboat be after 5 seconds if the initial velocity of the speedboat is 4 m/s? Solution: a = 2 m/s 2 u = 4 m/s t = 5 s final velocity = v v = u + at = 4 + 2×5 = 14 m/s 2) A vehicle has an acceleration of 5 m/s2. WebAverage Speed = (Total distance)/ (Total Time) = (1800 + 1800)/ (30 + 45) = 3600/75 = 48 km/hr. Hence the correct option here is C) 48 km/hr.
