Explanation:

Buoyant force = Weight of water displaced.

=mg=2×9.8N=19.6N.

Thrust is force

  • Mass=2kg
  • Acceleration due to gravity=g=9.8m/s^2

Using Newtons Second law

\boxed{\sf Force=Mass\times Acceleration}

\\ \qquad\quad\sf{:}\dashrightarrow Thrust=2(9.8)

\\ \qquad\quad\sf{:}\dashrightarrow Thrust=19.6N

Una esfera de radio 0.4m tiene una masa de 300kg, se desea sumergir en agua para saber si flota o no. En este ejercicio use la d
iragen [17]

Answer:

La esfera no flotará pero se hundirá cuando se coloque en el agua porque su densidad es mayor que la del agua.

Explanation:

De la pregunta anterior, se obtuvieron los siguientes datos:

Radio (r) de la esfera = 0,4 m

Masa de esfera = 300 Kg

Densidad del agua = 1000 Kg / m³

A continuación, determinaremos el volumen de la esfera. Esto se puede obtener de la siguiente manera:

Radio (r) de la esfera = 0,4 m

Pi (π) = 3,14

Volumen (V) de la esfera =?

V = 4/3 πr³

V = 4/3 × 3,14 × 0,4³

V = 12,56 / 3 × 0,064

V = 0,27 m³

A continuación, determinaremos la densidad de la esfera. Esto se puede obtener como se ilustra a continuación:

Masa de esfera = 300 Kg

Volumen de esfera = 0,27 m³

Densidad de esfera =?

Densidad = masa / volumen

Densidad de la esfera = 300 / 0,27

Densidad de la esfera = 1111,11 Kg / m³

Comparando la densidad del agua y la de la esfera.

Sustancia >>>>>>> Densidad

Agua >>>>>>>>>>> 1000 Kg / m³

Esfera >>>>>>>>>> 1111,11 Kg / m³

De la ilustración anterior, podemos ver que la densidad de la esfera es mayor que la del agua.

Por lo tanto, la esfera no flotará sino que se hundirá cuando se coloque en el agua porque su densidad es mayor que la del agua.

A mis-hit golf ball flies straight upward. It reaches a height of 31.0 meters before falling back down. How fast was it going wh
Tema [17]

At the top most position when ball reach to height 31 m

The speed of the ball must be ZERO

now we can use kinematics to find the final speed of the ball when it will hit back the ground

the equation of kinematics will be

v_f^2 - v_i^2 = 2 ad

v_f^2 - 0^2 = 2(9.8)(31)

v_f^2 = 607.6

v_f = 24.65 m/s

so it will hit the ground at speed 24.65 m/s
