Good Day
Problem:
What is the kinetic energy of a baseball with a mass 2 kg moving at a speed of 4 m/s?
Given Data:
m (mass) = 2 kg
v (velocity) = 4 m/s
K.E. (kinetic energy) = ? unknown
Solution:
The formula for Kinetic Energy is, K.E. = 1/2mv²
K.E. = 1/2mv²
= 1/2 × 2 kg × (4 m/s)²
= 1/2 × 2 kg × 16 m²/s²
= 16 kg.m²/s²
= 16 J
Answer:
16 J or 16 kg.m²/s²
