Let v⃗(t) be the velocity of a particle. Which statements are correct?

Select all that apply

• Option A

  |dv⃗/dt| and d|v⃗|/dt are always equal

• Option B

  |dv⃗/dt| and d|v⃗|/dt may be equal

• Option C

  d|v⃗|/dt can be zero while |dv⃗/dt| is nonzero

• Option D

  d|v⃗|/dt≠0 implies |dv⃗/dt|≠0
