Question

A soccer 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: ).

Answer 1

The formula for calculating kinetic energy (KE) is  0.5 * m*v^2.
m is mass
v is velocity

plunging the values

500=0.5*m*50*50
m=0.4kg
mass of the soccer ball is 0.4kgs

Answer 2

Answer:

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
