Una flecha se dispara verticalmente hacia arriba con una velocidad inicial de 80 ft/s. ¿Cuál es su altura máxima?

La altura máxima de la flecha es 99.459 pies

Explanation:

Los parámetros dados son;

La vertical inicial con la que se dispara la flecha, u = 80 pies / s

La distancia vertical recorrida por la flecha viene dada por la siguiente ecuación de movimiento;

v² = u² - 2 · g · s

Dónde;

v = La velocidad final de la flecha = 0 a la altura máxima

s = la altura de la flecha, = Altura máxima

u = La velocidad vertical inicial de la flecha

g = La aceleración debida a la gravedad = 32,17405 pies / s²

Por lo tanto, tenemos;

0² = 80² - 2 × 32.17405 ×

80² = 2 × 32.17405 ×

6400 = 2 × 32.17405 ×

= 6,400/(2 × 32.17405 ) ≈ 99.459 ft

= 99.459 ft

La altura máxima= 99.459 ft

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
