Sample questions from this chapter

Which quantity is necessarily a vector?
  1. Displacement ✓
  2. Distance
  3. Speed
  4. Temperature
Answer: A. Displacement has magnitude and direction and obeys vector addition. Distance, speed and temperature are scalars.
Why not B: Distance has magnitude only and accumulates path length.
Why not C: Speed is the scalar magnitude of velocity.
Why not D: Temperature carries magnitude and unit but no spatial direction.
A 20 m s⁻¹ vector is directed 30° above +x. What is its y-component?
  1. 17.3 m s⁻¹
  2. 20.0 m s⁻¹
  3. 10.0 m s⁻¹ ✓
  4. 5.0 m s⁻¹
Answer: C. Ay = A sin30° = 20 × 0.5 = 10.0 m s⁻¹.
Why not A: This uses cosine and obtains the x-component.
Why not B: This reports the full magnitude without resolving it.
Why not D: This multiplies by sin²30° instead of sin30°.
A boat moves north at 25 km h⁻¹ while current is 10 km h⁻¹ at 60° east of south. What is the resultant speed?
  1. 21.8 km h⁻¹ ✓
  2. 15.0 km h⁻¹
  3. 31.2 km h⁻¹
  4. 35.0 km h⁻¹
Answer: A. The angle between velocities is 120°, so R = √(25²+10²+2·25·10 cos120°) ≈ 21.8 km h⁻¹.
Why not B: This subtracts full speeds as if current were due south.
Why not C: This treats the included angle as 60° instead of 120°.
Why not D: This adds speeds as if both pointed north.
