Answer:

The formula for kinetic energy is K.E. = 1/2 mv 2 , where "m" stands for mass and "v" stands for velocity. Kinetic energy is typically measured in units of Joules, and 1 Joule is equal to 1 kilogram-meters squared per second squared.

a kid is flying a kite 58 meters above the level ground. a small lead sphere is dropped from the kite. calculate the amount of t

Fynjy0 [20]

This is the formula you need to memorize:

D = 1/2 · a · T²

Distance = (1/2) · (acceleration) · (Time²)

This formula tells the distance an object falls in any amount of time.

This question tells you the distance (58m), and you know the acceleration (gravity, 9.8 m/s²), so you can use this formula to find the time.

Distance = (1/2) · (acceleration) · (Time²)

58m = (1/2) · (9.8 m/s²) · (Time²)

Divide each side by (4.9 m/s²) : Time² = (58/4.9) seconds²

Take the square root of each side: Time = 3.44 seconds
