At what point in its path does a baseball that is hit to the outfield have its minimum vertical speed?

Physics
1 answer:
ioda3 years ago
5 0

Answer:

At the point when it reaches its maximum height (answer C)

Explanation:

As soon as the ball leaves the bat is has not only horizontal component of the velocity, but also vertical, which allows it travel upwards in its trajectory.

When it reaches its maximum elevation, and the trajectory starts curving down, is when the velocity of the baseball is just horizontal (the vertical component has been reduced to zero due to the constant action of the acceleration of gravity which was slowing down it ascending pattern.

After that point, the ball starts gaining now vertical velocity being accelerated towards the center of the Earth due to gravity. At the maximum height of its path is when the vertical component of the velocity switches from positive (pointing up) to negative (pointing down) going through zero magnitude.

The lower part of the walls of a house near the floor appear dump and begin to to peel off a few years after construction ,why a
kramer

Because of moisture-laden walls, climatic circumstances, Paints of lower grade the lowest portion of a house's walls near the floor seem cheap and start to peel off a few years after completion.  

<h3 /><h3>How can one minimize that risk?</h3>

we can minimize this risk by

  • Avoid getting water on the painted surfaces.
  • Control the surrounding surfaces' condensation and humidity.
  • Before painting, give the surfaces a thorough cleaning.
  • Only paint freshly cleaned surfaces.
  • Defend against heat and sunshine on the covered surfaces.
  • Pick the appropriate primer and paint.
  • Use effective painting techniques.
  • Away from the coated surfaces, keep corrosive materials.

A 12.0 V battery has as 80.0 Ohm
Vesna [10]
  • Potential difference=V=12V
  • Resistance=80ohm=R
  • Current be I

Using ohms law

\\ \sf\longmapsto \dfrac{V}{I}=R

\\ \sf\longmapsto I=\dfrac{V}{R}

\\ \sf\longmapsto I=\dfrac{12}{80}

\\ \sf\longmapsto I=0.15A

Two identical twins hold on to a rope, one at each end, on a smooth, frictionless ice surface. They skate in a circle about the
777dan777 [17]

Answer:

Part a)

L = 2683.2 kg m^2/s

Part b)

v' = 8.60 m/s

Part c)

W = 4326.7 J

Explanation:

Part a)

As we know that there is no external torque on the system of two twins

so here we will use

L = mv r + mvr

L = 2(78 \times 4.30 \times 4)

L = 2683.2 kg m^2/s

Part b)

Since angular momentum is conserved here as there is no external torque

so we will have

2(m v r) = 2( m v' \frac{r}{2})

v' = 2v

v' = 8.60 m/s

Part c)

Work done by both of them = change in kinetic energy

so we have

W = 2(\frac{1}{2}mv'^2 - \frac{1}{2}mv^2)

W = m(v'^2 - v^2)

W = 78(8.60^2 - 4.3^2)

W = 4326.7 J
