Three projectiles are launched from the same level on flat ground. Each reaches the same maximum height before returning to the ground, but projectile 3 (in blue) has the largest range, followed by projectile 2 (in green). Projectile 1 has the smallest range (in red).

Rank the three from largest to smallest according to:

Their time of flight

  1. 3>2>1
  2. 1>2>3
  3. 1=2=3

Their initial vertical component of velocity

  1. 3>2>1
  2. 1>2>3
  3. 1=2=3

Their initial horizontal component of velocity

  1. 3>2>1
  2. 1>2>3
  3. 1=2=3

Their initial speed

  1. 3>2>1
  2. 1>2>3
  3. 1=2=3
