  1. A spring toy launches a ball from level ground with a horizontal part of 4 m/s and a vertical part of 7.35 m/s. With no air, how far away does it land, Bo?

  2. A spring toy launches a ball from level ground with a horizontal part of 2.5 m/s and a vertical part of 14.7 m/s. With no air, how far away does it land, Esme?

  4. In the trajectory grid, what are the ball's velocity parts at 1 s, Jun?

    • 2.5 m/s across, 4.9 m/s up
    • 2.5 m/s across, 9.8 m/s down
    • 2.5 m/s across, 14.7 m/s up
    • 0 across, 4.9 m/s up

  5. In the trajectory grid, when is the ball at its highest point, Kira?

    Use the picture in question 3.

    • 1 s
    • 1.5 s
    • 3 s
    • 2 s

  6. In the trajectory grid, what is the vertical part of the velocity at 2.5 s, Luz?

    Use the picture in question 3.

    • 9.8 m/s upward
    • 24.5 m/s downward
    • 0 m/s
    • 9.8 m/s downward

  7. Milo says a launched ball is completely stopped at the top of its arc. Agree or disagree?

    • Agree: both parts of its motion stop
    • Agree: the whole flight takes the time to the top
    • Agree: steeper launches go farther
    • Disagree: it still moves sideways

  8. Pia says a ball's whole flight takes twice as long as reaching the top, on level ground with no air. Agree or disagree?

    • Disagree: the horizontal part is v sin θ
    • Agree: up and down take equal times
    • Disagree: the flight equals the time to the top
    • Disagree: steeper launches fall faster

  9. A ball with a horizontal part of 3 m/s must land 6 m away on level ground. What vertical part does it need, Ren?

    • 4.9 m/s
    • 19.6 m/s
    • 9.8 m/s
    • 2 m/s

  10. To double a ball's time in the air, what should Tala double?

    • The horizontal part of the launch
    • The vertical part of the launch
    • The range
    • The ball's mass

  11. A 45° launch on level ground has its speed doubled. With no air, what happens to its range, Zee?

    • It doubles
    • It stays the same
    • It halves
    • It becomes 4 times as far

About this worksheet

Objects launched at an angle. Every version has 10 questions, and the answer key prints on the second page.

What your child will learn

  • I can split a launch velocity into a horizontal part (v cos θ) and a vertical part (v sin θ).
  • I can find the time to the top (vertical part ÷ g), the highest point ((vertical part)² ÷ 2g), the whole flight (twice the time to the top) and the range (horizontal part × flight time).
  • I can read a trajectory grid. The horizontal arrow stays the same, the vertical arrow shrinks to 0 at the top and then grows downward, and the ball is not stopped at the top.
  • I can compare launch angles: 45° goes farthest on level ground, 30° and 60° tie, and steeper launches stay up longer.

Standard: supports HS-PS2-1

Words to know

launch angle: The angle between the launch direction and the ground

horizontal part: The sideways part of the launch velocity: v cos θ

vertical part: The upward part of the launch velocity: v sin θ

time of flight: Time from launch until landing

range: How far away it lands on level ground

Common mistakes

Your child mixed up the trip to the top with the whole flight. Going up and coming down take equal times, so the whole flight is twice the time to the top.

Your child left out the 2 in v² = 2gh. The highest point is (vertical part)² ÷ (2 × 9.8).

Your child thought the ball stops at the top. Only the vertical motion stops; the horizontal part keeps going, and gravity still acts.

Questions parents ask

What is the most common mistake with objects launched at an angle?

Your child mixed up the trip to the top with the whole flight. Going up and coming down take equal times, so the whole flight is twice the time to the top.
