Hi There , Please I need your help and I hope you can help me !


1) What is the kinetic energy of an aircraft with a mass of 2.510^5 kg travelling at a speed of 310^2 m/s ?


2) What is the mathematical relationship between a^n and a^-n ? Explain



Thank you so much !

Kinetic Energy = (1/2)mv².

where m = mass in kg= 2.5 10⁵kg = 250000 kg, v = velocity in m/s = 310² m/s = 300 m/s

Kinetic Energy = (1/2)250000300² = 0.5 250000 300 * 300

                         = 1.125 × 10¹⁰  Joules.


2)  Relationship between aⁿ and a⁻ⁿ   

a⁻ⁿ  =   1 / aⁿ

or

aⁿ  =   1 / a⁻ⁿ
