A59 g arrow is shot straight up into the air with a speed of 25 m/s. it reaches a maximum height of 30.8878 m. find the initial kinetic energy. the acceleration of gravity is 9.8 m/s 2 . answer in units of j.

18.44 J

Explanation:

Kinetic energy is the energy possessed by objects due to the fact that they are moving. It is half the product of the objects mass and the square of its velocity

K.E = 0.5mv²

     = 0.5 * 0.059 kg * (25 m/s)²

     = 18.44 J

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
