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

i think it's 35 meters
