1. A train has 90,000 j of potential energy at the top of a hill friction rob it of 18,000j on the way down how much kinetic energy remains 2. A Car driving down a long hill on the Highway has 20,000 J of Kinetic Energy, has 5,000J of Potential Energy left, and has lost 4,000 J due to friction. What was its Initial Potential Energy at the top of the hill?

3. A bicycle lost 200 J of Thermal Energy, has 1200 J of Kinetic Energy as it rolls down the trail, and still has 1600 J of Potential Energy before it hits the bottom! What is its TOTAL ENERGY?

4. If a Motorcycle had a Total Energy of 10,000 J, and 4,000 J of Potential Energy and 4,000 J of Kinetic Energy then how much Thermal Energy has it lost due to Friction?

(x3 + 6x2 + 2x - 6) • (x - 1)

step-by-step explanation:

polynomial long division :

3.2     polynomial long division

dividing :   x4+5x3-4x2-8x+6

                              ("dividend")

by         :     x-1     ("divisor")

dividend     x4   +   5x3   -   4x2   -   8x   +   6

- divisor   * x3     x4   -   x3            

remainder         6x3   -   4x2   -   8x   +   6

- divisor   * 6x2         6x3   -   6x2        

remainder             2x2   -   8x   +   6

- divisor   * 2x1             2x2   -   2x    

remainder               -   6x   +   6

- divisor   * -6x0               -   6x   +   6

remainder                     0

quotient :   x3+6x2+2x-6   remainder:   0

answer: 0.64
