If a ball is dropped from a height​ (H) its velocity will increase until it hits the ground​ (assuming that aerodynamic drag due to the air is​ negligible). During its​ fall, its initial potential energy is converted into kinetic energy. If the ball is dropped from a height of 720 centimeters​ [cm], and the impact velocity is 39 feet per second​ [ft/s], determine the value of gravity in units of meters per second squared ​[m/s2​].

Answer

Step-by-step explanation:

so the velocity is 39 feet per sec so the impact is 720 cm from the ground

take 720 * 39 sq
