Formula: H = (v₀·sinθ)² ÷ (2g)

Step-by-Step Breakdown

1. Values used:

2. Launch speed = 20

3. Launch angle = 45 °

4. Gravity = 9.81 m/s²

6. Maximum height = 10.194

Did this calculator solve your problem today?

The math behind it

Only the vertical velocity v₀·sinθ matters: H = (v₀·sinθ)² ÷ (2g).

20 m/s at 45° → 10.19 m.

When is height greatest?

At a 90° (straight up) launch, where all the speed is vertical.
