Answer: the final mass of the solid is 176 grams.

Step-by-step explanation:

The "change" between two quantities, one initial Qi and one final Qf is defined as:

Change = Qf - Qi.

In this case, the quantity is mass, and we know that the initial mass is 260 grams.

And we also know that the change is -84 grams.

Then we have the equation:

Qf - 260 g = -84g

Qf = -84g + 260g = 176g

So the final mass of the solid is 176 grams.

The velocity,v of a missile is related to time t, By the equation v=5t^2+3t+1.calculate the time at which the velocity is minimu
Cloud [144]

Answer:

  • time: t = -0.3
  • minimum: v = 0.55

Step-by-step explanation:

For quadratic ax^2 + bx + c, the extreme value is found at x=-b/(2a). For your quadratic, the minimum is found at ...

  t = -(3)/(2(5))

  t = -0.3 . . . . . time of minimum velocity

__

The value of velocity at that time is ...

  v = 5(-0.3)^2 +3(-0.3) +1 = 5(.09) -.9 +1

  v = 0.55 . . . . . value of minimum velocity
