Answer:
K.E = 3400 Joules.
Explanation:
Given the following data;
Mass = 30kg
Velocity = 15m/s
To find the kinetic energy;
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;
[tex] K.E = \frac{1}{2}*30*15^{2}[/tex]
[tex] K.E = 15*225 [/tex]
K.E = 3375 Joules.
To two (2) significant digits, the kinetic energy of the dog is 3400 Joules.
