Answer:

10 kg

Step-by-step explanation:

Formula for the kinetic energy:

½mv²

Find the mass:

= ½ × m × 10² = 500 joules

= 50 × m

m = 500 ÷ 50

m = 10 kg

The answer is 10 kg.

Answer:

10 kg

Step-by-step explanation

Step-by-step explanation:

Kinetic Energy = 1/2 * M (V square )

M is mass and V is velocity of the ball

500J = 1/2 *M *( 10)*(10)

M = 10 kg
