A 0.300 kg block is pressed against a spring with a spring constant of 8050 N/m until the spring is compressed by 6.00 cm. When

natita [175]

Answer:

a) $\mu_{k} = 0.704$ , b) $R = 0.312\,m$

Explanation:

a) The minimum coeffcient of friction is computed by the following expression derived from the Principle of Energy Conservation:

$\frac{1}{2}\cdot k \cdot x^{2} = \mu_{k}\cdot m\cdot g \cdot \Delta s$

$\mu_{k} = \frac{k\cdot x^{2}}{2\cdot m\cdot g \cdot \Delta s}$

$\mu_{k} = \frac{\left(8050\,\frac{N}{m} \right)\cdot (0.06\,m)^{2}}{2\cdot (0.3\,kg)\cdot (9.807\,\frac{m}{s^{2}} )\cdot (7\,m)}$

$\mu_{k} = 0.704$

b) The speed of the block is determined by using the Principle of Energy Conservation:

$\frac{1}{2}\cdot k \cdot x^{2} = \frac{1}{2}\cdot m \cdot v^{2}$

$v = x\cdot \sqrt{\frac{k}{m} }$

$v = (0.06\,m)\cdot \sqrt{\frac{8050\,\frac{N}{m} }{0.3\,kg} }$

$v \approx 9.829\,\frac{m}{s}$

The radius of the circular loop is:

$\Sigma F_{r} = -90\,N -(0.3\,kg)\cdot (9.807\,\frac{m}{s^{2}} ) = -(0.3\,kg)\cdot \frac{v^{2}}{R}$

$\frac{\left(9.829\,\frac{m}{s}\right)^{2}}{R} = 309.807\,\frac{m}{s^{2}}$

$R = 0.312\,m$

6. What is the resultant force on each car below? Remember TWO pieces of

tamaranim1 [39]

Explanation:

In first case, the forces on LHS and on RHS is the same i.e. 3 N. The force acting on the car is balanced force. As a result, the car will not move at all.

In second case,

Force on RHS = 2000 N

Force on LHS = -6000 N

Net force acting on it is given by :

F = 2000+(-6000)

= -4000 N

Hence, this is the required solution.

PLEASE HELP!!!! Which is the best example of a non-inertial frame of reference? (1 point)

Sergeu [11.5K]

Answer: B

Explanation:

A - No, because this has nothing to do with curves

B - Yes, because it explains gravity and it it forced down by gravity

C - No, because this has nothing to do with a rocket ship an dhow much it can travel per #.

D - No, because This has nothing to do with a boat on water and it explain nothing about gravity or how fast it is.

I Hope This Helped!

Newton's Law of Gravity states that if the mass of one object doubles, the gravitational pull on a second object will

OLEGan [10]

Answer:

It will double.

Explanation:

Newton's Law of Gravity states that $F_G=\frac{Gm_1m_2}{r^{2}}$ , where G is the gravitational constant, r is the distance between the objects' centers, and $m_1$ and $m_2$ are the objects' masses. We just have simple math here: by doubling $m_1$ , we double the entire fraction. By doubling the entire fraction, we double the gravitational pull. Therefore, Newton's Law of Gravity states that if the mass of one object doubles, the gravitational pull on a second object will double.

I hope this helps you understand it! Have a great day, 'kay?
