Superman lived on another planet where the acceleration due to gravity is 23.6 m/s2 . if a woman falls from a building that is 88.3 m tall, how long does he have to save her before she hits the ground?

Acceleration due to gravity = 2.6m/s²

Length of building = d = 88.3m

Time he needed before she hits the ground = ?
 we can find the time by using the formula;

D = 1/2at²

Now putting the value;

88.3 = (1/2) a t²

88.3 = 1/2 x 23.6 x t²

t² = 88.3 / 11.8

= 7.48

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."
