Question
Determine whether a scalar or a vector is described in (a) and (b). Explain your answers.(a) A small-craft warning reports $25 \mathrm{mi} / \mathrm{h}$ winds.(b) A small-craft warning reports $25 \mathrm{mi} / \mathrm{h}$ winds from the north.
Step 1
A scalar is a quantity that is fully described by a magnitude only. It is described by just a single number. A vector is a quantity that is fully described by both a magnitude and a direction. Show more…

Determine whether a scalar or a vector is described in (a) and (b). Explain your answers. (a) A ballistics test shows that a bullet hit a wall at a speed of $400 \mathrm{ft} / \mathrm{s}$ (b) A ballistics test shows that a bullet hit a wall at a speed of $400 \mathrm{ft} / \mathrm{s}$ perpendicular to the wall.
A small airplane is flying at $50 \mathrm{m} / \mathrm{s}$ toward the east. A wind of $20 \mathrm{m} / \mathrm{s}$ toward the east suddenly begins to blow and gives the plane a velocity of $70 \mathrm{m} / \mathrm{s}$ east. a. Which vector is the resultant vector? b. What is the magnitude of the wind velocity?
