Para que ángulo el alcance es igual a la altura máxima en un lanzamiento de proyectil ideal sobre un plano horizontal. Translation: For which angle the range equals the maximum height in an ideal projectile launch on a horizontal plane. a) 45º b) 60º c) 76º d) 90º

Explanation:

In projectile,

Maximum height = and range =

u = velocity of the body

= angle of launch

g = acceleration due to gravity

If the range equals the maximum height in an ideal projectile launch on a horizontal plane, this means;

since

The angle at which the range equals the maximum height in an ideal projectile launch on a horizontal plane is approximately 76°

another example of kinetic energy would be,

kinetic energy   >     moving energy
