a gun tilted upward at 30 degrees fires a bullet with a speed of 215 m/s. what is the bullets velocity parallel to the ground
Initial velocity was 215 m/s at θ=30° upwards of the horizontal.
The horizontal component of the velocity is its projection on the horizontal, namely: magnitude = 215cos(θ) and direction: along the horizontal.
