A projectile fired from a gun has initial horizontal and vertical components of velocity equal to 30 m/s and 40 m/s, respectively.
-At what angle is the projectile fired (measured with respect to the horizontal)?
A)37°
B)40°
C)45°
D)53°
E)60°

The angle θ can be found using the tangent function: tan(θ) = vertical velocity / horizontal velocity = 40/30. Solving for θ gives θ = arctan(4/3), which is approximately 53°.
