A spring toy launches a ball with a vertical part of 4.9 m/s. With no air, how long does it take to reach the top, Ari?
A spring toy launches a ball with a vertical part of 14.7 m/s. With no air, how long does it take to reach the top, Bo?
A spring toy launches a ball with a vertical part of 24.5 m/s. With no air, how long does it take to reach the top, Esme?
4.
In the trajectory grid, what does the vertical arrow show at the top of the arc, Jun?
- 9.8 m/s upward
- 0 m/s
- 9.8 m/s downward
5.
In the trajectory grid, what happens to the horizontal arrow along the arc, Kira?
Use the picture in question 4.
- It grows
- It stays at 3 m/s
- It drops to 0 at the top
6.
In the trajectory grid, how fast is the ball moving at the top, Luz?
Use the picture in question 4.
- 9.8 m/s
- 3 m/s, sideways
- 0 m/s; it has stopped
7.
A ball is launched at 10 m/s, 60° above the ground. What is its horizontal part, Noah?
- 5 m/s
- 6 m/s
- 8.7 m/s
8.
A ball is launched at 10 m/s straight up, 90° above the ground. What is its horizontal part, Pia?
- 0 m/s
- 10 m/s
- 5 m/s
9.
A ball reaches the top of its arc after 1 s. With no air, when does it land on level ground, Ren?
- At 2 s
- At 1 s
- At 4 s
10.
Where along its path is a ball at its highest, on level ground with no air, Zee?
- At the very end
- Halfway across
- Right at the start

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.
