An ocean liner approaches a peer at 20km/h. When the ocean liner is 10 km away, the captain sends a speedboat to the pier to pick up the harbour pilot, who will help dock the ocean liner. The speedboat takes 12 min to get to the pier.
a) How long would the speedboat take to return to the ocean liner if it maintains the same speed?
b)Find the displacement of the speedboat during the round trip and the distance covered by the speedboat during the round trip.
xab(t) = 1/2 aabt^2 + voab + xoab
The Attempt at a Solution
a) (0) = (0) + (8.33)t + (0)
