Answer:
Mass, M = 0.75kg
Explanation:
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.
Given the following data;
Kinetic energy = 150J
Velocity = 20m/s
Making mass the subject formula;
[tex] M = \frac{2K.E}{V^{2}}[/tex]
Substituting into the equation, we have;
[tex] M = \frac{2*150}{20^{2}}[/tex]
[tex] M = \frac{300}{400}[/tex]
Mass, M = 0.75kg
