Answer:
The change in velocity is 5.5 km/h
Explanation:
The initial velocity with which the sailboat is travelling, v₁ = 10 km/h
The final velocity with which the sailboat is travelling, v₂ = 15.5 km/h
The change in velocity, Δv, is the difference between final velocity, v₂ and the initial velocity, v₁, as follows;
Mathematically, Δv = v₂ - v₁
By substituting the given values, we have;
Δv = 15.5 km/h - 10 km/h = 5.5 km/h
The change in velocity, of the sailboat Δv = 5.5 km/h.
