Kinetic Energy = (1/2)mv².

where m = mass in kg= 2.5 * 10⁵kg = 250000 kg, v = velocity in m/s = 3*10² m/s = 300 m/s

Kinetic Energy = (1/2)*250000*300² = 0.5 * 250000 * 300 * 300

                         = 1.125 × 10¹⁰  Joules.

Refer to the above graph to answer questions 1 through 5. 1. Lines A and B form what type of system?
xeze [42]

Answer:

Lines A and B form a consistent independent system

Step-by-step explanation:

we know that

A consistent system of equations has at least one solution

In this problem

The system of Line A and Line B has only one solution, since it has only one point of intersection.

and the Line A is different to Line B

therefore

Lines A and B form a consistent independent system

(independent because Lines A and B are different)
