For an object whose velocity in ft/sec is given by v(t) = −t^2+ 6, what is its displacement, in feet, on the interval t = 0 to t
zheka24 [161]
Answer: 9 ft

Explanation:
Since the velocity is the derivative of position vector and the displacement is the difference between two position vectors, the displacement is computed as a definite integral of velocity for a time interval (from one time to another time). 

Because the time interval is t =0 second to t = 3 seconds, the displacement is calculated as

\text{displacement} = \int_{0}^{3} {v(t) dt}
\\
\\ = \int_{0}^{3} {(-t^2 + 6) dt}
\\
\\ = \left [ -\frac{t^3}{3} + 6t \right ]_{0}^{3}
\\
\\ = \left ( -\frac{(3)^3}{3} + 6(3) \right ) - \left ( -\frac{(0)^3}{3} + 6(0) \right )
\\
\\ \boxed{\text{displacement} = 9}

Hence, the displacement is 9 ft.

Step-by-step explanation:

15x + 5y = 10

5y = -15x + 10

y = -15x/5 + 10/5

y= -3x + 2

y= mx + c

Slope m= -3 and y intercept = 2
