A bucket of water with mass 5 kg sits on the ground with a coefficient of static friction of 0.35. What is the maximum force of

static friction?
Physics

Answer:

The force of static friction is 17.15 N

Explanation:

It is given that,

Mass of the bucket, m = 5 kg

The coefficient of static friction is, \mu=0.35

We need to find the maximum force of static friction. It is given by :

F=\mu mg

F=0.35\times 5\ kg\times 9.8\ m/s^2

F = 17.15 N

So, the force of static friction is 17.15 N. Hence, this is the required solution.

2. ¿Puede haber trabajo en un sistema si no hay movimiento
Andru [333]

Answer:

d. No, porque la ecuación de trabajo lo define.

Explanation:

En Física, el trabajo realizado se puede definir como la cantidad de energía transferida cuando un objeto o cuerpo se mueve a lo largo de una distancia debido a la acción de una fuerza externa.

Matemáticamente, el trabajo realizado viene dado por la fórmula;

W = F * d

<u>Dónde;</u>

  • W es el trabajo realizado.
  • F representa la fuerza que actúa sobre un cuerpo.
  • d representa la distancia recorrida por el cuerpo.

Por lo tanto, podemos deducir de la definición de trabajo y su fórmula que el trabajo se realiza cuando un objeto (cuerpo) se mueve una distancia o experimenta cualquier forma de desplazamiento mientras transfiere energía.

A playground merry-go-round of radius R = 1.80 m has a moment of inertia I = 270 kg · m2 and is rotating at 8.0 rev/min about a
Arte-miy333 [17]

Answer:

\dot n = 6.042\,rpm

Explanation:

The final angle speed of the merry-go-round is determined with the help of the Principle of Angular Momentum Conservation:

(270\,kg\cdot m^{2})\cdot \left(8\,rpm\right) = [270\,kg\cdot m^{2}+(27\,kg)\cdot (1.80\,m)^{2}]\cdot \dot n

\dot n = 6.042\,rpm

A train is moving with a velocity of 70 km/h.
hodyreva [135]

Answer:

B: It is moving north.

Explanation:

We are told that a train is moving with a velocity of 70 km/h.

Now, we are also told that the positive direction is north.

This means that the train is moving in the northern direction.

We can't say if it is speeding up or not because we are not given the acceleration.

Thus, option B is correct

A 5.22-kg object passes through the origin at time t = 0 such that its x component of velocity is 5.10 m/s and its y component o
Mamont248 [21]

The magnitude of the object's velocity is

         √ (5.1² + 2.82²)  =  √ (33.9624)  =  5.828 m/s .

Kinetic energy = (1/2) (M) (speed²)

                       =  (1/2) (5.22 kg) (5.828 m/s)²

                       =     (2.61 kg) (33.9624 m²/s²)

                       =          88.64    kg-m²/s²

                       =          88.64  Joules
