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

allochka39001 [22]

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.

Bess [88]

Answer:

La presión neumática para levantar un automóvil de 17,640 newtons es 220,500 pascales.

Explanation:

Asumiendo que la presión ( $P$ ), medida en pascales, tiene una distribución uniforme sobre la superficie del pistón, se calcula a partir de la siguiente expresion:
