Asoccer ball is traveling at a velocity of 50 m/s. the kinetic energy of the ball is 500 j. what is the mass of the soccer ball? (formula: ).

0.4 kg

Explanation:

Information given;

Mass of ball = ?

Velocity = 50 m/s

Kinetic Energy = 500J

The formular relating these parameters is given as;

K.E = 0.5 * Mass * Velocity²

500 = 0.5 * M * 50²

M = 500 / (0.5 * 50 * 50)

M = 500 / 1250

M = 0.4 kg

answer; i believe that the correct answer is (a); a large rock being weathered by wind and rain;

3 hours because it is a decent distance.
