The Answer is (32/20)^2=2.56times the kinetic enrgy at 20 m/s 2.56x4500

Problem The kinetic energy (k) of moving object varies jointly with it mass (m) and the square of its velocity(v). If an object has a mass of 22.5 kilgorams and moving with a velocity of 20 meters per second has a kinetic energy of 4500 joules, fined it kinetic energy when the velocity is 32 meters per second.

Write a 250 word summary of the above problem your written work should include but necssarily to the following. An explanation of the problem, a review of the mathematical concept involved a critique of the method used to obtain the solution and an interpertation of the answer please help me.

Everything is the same but the velocity.

Ke proportional to v^2

so proportional to

(32/20)^2 = 1.6^2 = 2.56 times original Ke

2.56 * 4500 = 11,520

Can someone help me write a 250 word summard of the above problem, wriiten work should include but necessarily limited to the following. An explaniation of the problem, a review of the mathmetical concept invovled a critque of the method used ot obtain the solution, and an interpertation of the answer.
