Suppose a car's momentum is calculated to be 36000 . the mass of the car is 1,500 kg. what is the magnitude of the velocity of the car?

The magnitude of the velocity of the car is 24 m/s .

Step-by-step explanation:

Given : A car's momentum is calculated to be 36000 .

          the mass of the car is 1500 kg.

To find: What is the magnitude of the velocity of the car.

Formula used:

           Momentum =mass × velocity

Explanation:

We are given that momentum of the car =36000 .

                                  Mass of the car = 1500 kg .

  Plugging the given value in the above formula

                 Momentum =mass × velocity

                               36000 = 1500 × velocity

  On dividing both side by 1500 we get ,

                              velocity   =    24 meter/second

Therefore,   The magnitude of the velocity of the car is 24 m/s .

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
