A ball moves in a straight line has an acceleration of a(t) = 2t + 5. Find the position function of the ball if its initial velo
Vlad1618 [11]

Answer:

s(t) = frac{t^3}{3} + \frac{5t^2}{2} - 3t + 12

Step-by-step explanation:

Relation between acceleration, velocity and position:

The velocity function is the integral of the acceleration function.

The position function is the integral of the velocity function.

Acceleration:

As given by the problem, the acceleration function is a(t) = 2t + 5

Velocity:

v(t) = \int a(t) dt = \int (2t+5) dt = \frac{2t^2}{2} + 5t + K = t^2 + 5t + K

In which K is the constant of integration, which is the initial velocity. So K = -3 and:

v(t) = t^2 + 5t - 3

Position:

s(t) = \int v(t) dt = \int (t^2 + 5t - 3) = \frac{t^3}{3} + \frac{5t^2}{2} - 3t + K

In which K, the constant of integration, is the initial position. Since it is 12:

s(t) = frac{t^3}{3} + \frac{5t^2}{2} - 3t + 12

lions [1.4K]
<h2>Answer:</h2>

The correct statement that is used when a scatter plot is constructed is:

The independent variable is the input variable and should be represented by the x-axis.

<h2>Step-by-step explanation:</h2>

We know that while plotting a graph or a scatter plot the x-axis which is the horizontal axis of the plot represents the input value or the value of the independent variable and the output value i.e. the value of the function corresponding to the input value is represented by the y-axis.

As the value of the output is evaluated corresponding to the input value hence the variable y is also known as the dependent variable and is represented by the y-axis.
