A ship travels in a straight path between two ports. Figure 1.1 presents the ship’s speed-time graph for the opening 100 minutes of the trip between the two ports.
(a)[2]
Calculate the highest acceleration in the first 100 minutes of the ship’s journey.
(b)[3]
Calculate the total distance covered by the ship from time = 42 min to time = 100 min.
(c(i))[2]
Calculate the resultant force on the ship.
(c(ii))[1]
Explain why the force on the ship from the ship’s engine is larger than the value you calculated in (c)(i).
