A 30 kg dog runs at a speed of 15 m/s. What is the dog's kinetic energy (in jewels)? Round the answer to two significant digits.

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;

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;

K.E = 3375 Joules.

To two (2) significant digits, the kinetic energy of the dog is 3400 Joules.

the answer to this is proletariats.

hope this : )
