Acar with a mass of 600 kg is traveling at a velocity of 10m/s. how much kinetic energy does it have?

E = 1/2 * m * v^2 = 1/2 * (600 kg) * (10 m/s)^2 = 30000 J = 30 kJ

your answer is d 2,500

step-by-step explanation:

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
