Answer:
25v²
Step-by-step explanation:
The kinetic energy in joules of a 50-kilogram runner running at v meters per second is modeled by the equation
Solution:
Kinetic energy is the energy of a body due to its motion. The kinetic energy of a body is maintained until there is a change in velocity. Kinetic energy can also be defined as the work done in accelerating a body from rest to a specified velocity. The SI unit is in Joules (J)
The formula for kinetic energy is:
K.E = (1/2)mv²
where m is the mass of the object and v is the velocity of the object.
Given that m = 50 kg and v = v, hence:
K.E = (1/2) * 50 * v² = 25v²
K.E = 25v²
