Question

Ella jogs down the street with a speed of 12 m/s. What is her kinetic energy if her mass is 58 kg?

Answer 1

4176 J

Step-by-step explanation:

Ella speed (V) = 12 m/s, Mass = 58 kg.

Kinetic energy of a body is the energy it possesses as a result of its motion. It is the energy (work) needed to cause a given body to move from rest to its final velocity. It is measured in Joules. The kinetic energy of a body is the same until its velocity changes.

Kinetic energy = 1/2 × m × V²

Kinetic energy = 0.5 × 58 × 12² = 4176 J
