Question 283889
Problem: The kinetic Energy (K) of a moving object varies jointly with its mass (m) and the square of its
velocity (v). If an object weighing 90 kilograms and moving with a velocity of 20 meters per second has a
kinetic energy of 4500 Joules, find its kinetic energy when the velocity is 32 meters per second.
---------------------
It's 4500*(32/20)^2
= 11520 Joules
