Launch at an Angle
Part of the Mechanics section of Coddy's Physics journey. Lesson 35 of 94.
Launched at v0 and an angle θ, split the velocity into components:
v0x = v0 cos θ, v0y = v0 sin θ
The horizontal part stays the same. The vertical part drops by 9.8 m/s every second and is zero at the top, where the ball still moves sideways.
At the top the vertical part is zero; the horizontal part is still vx.
Challenge
A fireworks shell is launched at 39.2 m/s at 30° above the ground. Find the time t it takes to reach the top of its path.
