Answer:

Mass = 2.50 kilograms.

Explanation:

Given the following data;

Velocity = 4.3m/s

Kinetic energy = 23.1J

To find the mass of the ball;

Kinetic energy can be defined as an energy possessed by an object or body due to its motion.

Mathematically, kinetic energy is given by the formula;

[tex] K.E = \frac{1}{2}MV^{2}[/tex]

Where;

K.E represents kinetic energy measured in Joules.

M represents mass measured in kilograms.

V represents velocity measured in metres per seconds square.

Substituting into the equation, we have

23.1 = ½m*4.3²

46.2 = 18.49m

Mass, m = 46.2/18.49

Mass, m = 2.498 ≈ 2.50kg
