Evaluate the indefinite integral. (Use C for the constant of integration.) a + bx? dx 8ax + bx

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?

Explain why you can omit the constant of integration when finding an integrating factor.

Differentiate the function.  u= (1/t -1/square root of t)^2
