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
