A particle is moving with the given acceleration function and initial conditions. Find the velocity function and the position fu
Lerok [7]

Answer:

The velocity function is the particle is v(t)=-2\cos (t)-4\sin (t)-1.

Step-by-step explanation:

The acceleration function of a moving particle is

a(t)=2\sin (t)-4\cos (t)

The initial conditions are v(0) = −3, s(0) = 5.

Integrate the acceleration function with respect to time to find the velocity function.

\int a(t)=\int (2\sin (t)-4\cos (t))dt

v(t)=-2\cos (t)-4\sin (t)+C_1

Use the initial condition v(0) = −3 to find the value of C₁.

-3=-2\cos (0)-4\sin (0)+C_1

-3=-2(1)-4(0)+C_1

-3=-2+C_1

-3+2=C_1

-1=C_1

So the velocity function is the particle is

v(t)=-2\cos (t)-4\sin (t)-1

Integrate the acceleration function with respect to time to find the position function.

\int v(t)=\int (-2\cos (t)-4\sin (t)-1)dt

s(t)=-2\sin (t)+4\cos (t)-t+C_2

Use the initial condition s(0) = 5 to find the value of C₂.

5=-2\sin (0)+4\cos (0)-(0)+C_2

5=-2(0)+4(1)+C_2

5=4+C_2

1=C_2

So, the position function is the particle is s(t)=-2\sin (t)+4\cos (t)-t+1.
