The sailboat is initially traveling at velocity of 10km/h. What is the change in velocity if the final velocity is 15.5km/h

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.

hi there!

your question asks at which segment does freezing occur.

since we're talking about water, the freezing point of water will be 32 degrees fahrenheit or below.

hope this ! ~
