Given the following velocity functions of an object moving along a line, find the position function with the given initial position v(t)=2t+4

Respuesta :

Answer:

The position of the particle as a function of times is given by

[tex]x(t)=t^{2}+2t+x(o)[/tex]  where [tex]x(0)[/tex] is the position of the particle at t = 0 secs.

Step-by-step explanation:

Give that

[tex]v(t)=2t+4[/tex]

we know that

[tex]v(t)=\frac{dx(t)}{dt}\\\\\therefore dx(t)=v(t)dt\\\\\int dx(t)=\int v(t)dt\\\\x(t)=\int v(t)dt[/tex]

Applying values we get

[tex]x(t)=\int (2t+4)dt\\\\x(t)=\int 2tdt+\int 4dt\\\\x(t)=\frac{2t^{2}}{2}+4t+c[/tex]

here 'c' is the constant of integration which represents the position of the particle at time t = 0 secs.

Thus we have

[tex]x(t)=t^{2}+2t+x(o)[/tex]
