- The kinetic energy E of an object varies jointly with the object’s mass m and the square of the object’s velocity v . An object with a mass of 50 kilograms traveling at 16 meters per second has a kinetic energy of 6400 joules. What is the kinetic energy of an object with a mass of 70 kilograms traveling at 20 meters per second?arrow_forwardFor the following exercises, find the slope of the lines that pass through each pair of points and determine whether the lines are parallel or perpendicular. 30. F=ma indicates that force (F) equals mass (m)times acceleration (a). Find the acceleration of a mass of 50 kg if a force of 12 N is exerted on it.arrow_forward
