It is the instantaneous speed of the bike rider.

Explanation:

At the mile marker, the measured speed gives the instantaneous speed of the bike rider.

The instantaneous speed is speed measured at a precise or instance of time.

 Speed is the rate of change of distance with time. It is a scalar quantity that only shows magnitude with no reference to direction.

  Velocity is the displacement divided by time. It has both magnitude and directions.

Average speed is measured over a period of time as the distance increases from the starting point.

From this, we can see that 13.5mph is the instantaneous speed of the bike rider.

Why does fluid pressure exist?
zubka84 [21]

Answer:

Fluid pressure from gravity is the weight of the fluid above divided by the area it is pushing on. Fluid pressure applies in all directions. Internal pressure of an object equals the external fluid pressure, otherwise the object could be crushed. Wind and heating can also create pressure.

A juggler is practicing with one ball. It takes 2.4 seconds for the ball to leave her hand and return to her hand. How fast did

The kinematics for the vertical launch we can enter the initial velocity is 11.76 m / s

Given parameters

  • Time t = 2.4 s

To find

  • Initial velocity

Kinematics is the part of physics that establishes the relationships between the position, velocity, and acceleration of bodies.

In this case we have a vertical launch

          y = y₀ + v₀ t - ½ g t²

Where y and y₀ are the final and initial positions, respectively, v₀ the initial velocity, g the acceleration of gravity (g = 9.8 m / s²) and t the time

   

With the ball in hand, its position is zero

         0 = 0 + v₀ t - ½ g t²

         v₀ t - ½ g t² = 0

         v₀ = ½ g t

Let's calculate

         v₀ = ½ 9.8 2.4

         v₀ = 11.76 m / s

In conclusion using kinematics for the vertical launch we can enter the initial velocity is 11.76 m / s
