A projectile is fired with an initial speed of 36.6 m/s at an angle of 42.2° above the horizontal on a long, flat firing range.

Determine:

(a) The maximum height reached by the projectile.

Answer :

Final answer:

The maximum height reached by the projectile, considering its initial speed and projection angle, and ignoring air resistance, is approximately 31.5 meters.

Explanation:

To determine the maximum height reached by a projectile, we need to consider the vertical motion of the projectile. The initial vertical velocity of our projectile can be calculated using the given initial speed and projection angle: initial vertical velocity = initial speed * sin(projection angle), which gives us approximately 24.8 m/s. The maximum height can then be found using the equation for the height of an object in free fall: height = initial vertical velocity^2 / (2 * gravity), ignoring the impact of air resistance. By substitifying the values, the maximum height equals to approximately 31.5 meters.
