The average velocity of Alyse is 0 m/s.

<h3>What is the average velocity of an object or a person?</h3>

The average velocity of a person is the average of all the velocities of moving as it moves.

Velocity on its own is the ratio of the displacement of a body and the time taken for that displacement.

Mathematically:

  • Average velocity = total displacement / time taken

Displacement is a vector quantity that measures the distance traveled by a moving body in a specific direction.

Hence, average velocity and velocity are both vector quantities.

Displacement takes a measure of the shortest possible distance along a straight line from the beginning of the motion until the end of the motion.

Calculating the average velocity of Alyse:

Assuming the initial direction is positive and n=backeard direction is negative:

Total displacement = 20 m + - (20 m)

Total displacement = 0 m

total time = 3 minutes

Average velocity = 0 m/ 3

Average velocity = 0 m/s

Luda [366]

Answer:

The time travel is

t=8 s

Explanation:

a= 2 \frac{m}{s^{2} } \\v=-6 \frac{m}{s} \\x=16m

x_{f}=x_{o}+v_{o}*t+\frac{1}{2} *a*t^{2}

x_{f}=0-6*t+\frac{1}{2} *2*t^{2}

t^{2}-6*t-16=0\\ using :\\\frac{-b+/-\sqrt{b^{2}-4*c*a } }{2} \\\frac{-(-6)+/-\sqrt{(-6)^{2}-4*(-16)*(1) } }{2}=\frac{3}{2} +/- \frac{10}{2} \\t_{1} = 2s \\t_{2} = 8s

Check

t_{2}=8s

x_{f}=x_{o}+v_{o}*t+\frac{1}{2} *a*t^{2}

x_{f}=0-6*+\frac{1}{2} *2*8^{2}

x_{f}=-48+64\\x_{f}=16
