A yellow ball with a mass of 2 kg is rolling across the floor at 3 m/s. A red ball with a mass of 3 kg is rolling across the
same floor at 3 m/s. Which ball has greater kinetic energy, and why?
A. The yellow ball has greater kinetic energy, because it is rolling at a higher position above the ground
B. The red ball has greater Kinetic energy, because it has a greater mass.
C. The yellow ball has greater kinetic energy, because it is rolling at a greater speed
D. The red ball has greater kinetic energy, because it is releasing more thermal energy.

The answer is B.

10/60

step-by-step explanation:

if you divide 10 by 60 the answer is 0.166666 while if you divide or solve the other problems it equals 0.6

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
