For small, slowly falling objects, the assumption made inEq. (i) of Problem 8 that the drag force is proportional to the velocity is a good one. For larger, more rapidly falling
objects, it is more accurate to assume that the drag force isproportional to the square of the velocity.

- 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_forwardFind an equation of the tangent line to the parabola y=3x2 at the point 1,3.arrow_forwardFind the constant of proportionality. y is directly proportional to x. If x=30, then y=15.arrow_forward
