During an off-day, Mike Trout, Shohei Ohtani, and Albert Pujols and having a pool party. They are tugging on a ring for some odd

reason (The Angels are weird…). Trout pulls with a force of 150 N directly north, Ohtani pulls directly east with a force of 100 N, and Pujols pulls southwest (225° clockwise from north) with a force of 200 N. What is the resultant force and what is the direction of the resultant force?

Answer:

\left \| F \right \| = 42.3 N

\theta = 11.7 degree north of west

Explanation:

Given data:

Force by trout 150 N

Force by Ohtani 100 N

Force by pujols 200 N

Net force is given as

F = 150 j - 200\times cos 45j + ( 100i - 200\times sin45 i)

F = (100 - 100\sqrt {2}) i + (150 - 100\sqrt{2}) j

\left \| F \right \| = \sqrt{(100 - 100\sqrt{2})^2 + (150 -100\sqrt{2})^2}

\left \| F \right \| = 42.3 N

Direction is

tan\theta = \left | \frac{150-100\sqrt{2}}{100-100\sqrt{2}} \right |

\theta = 11.7 degree north of west

katrin [286]

Answer:

90°

Explanation:

The angle will be 90° when momentum for a system can be conserved in one direction while not being conserved in another.

The example can be

If we apply force on an object horizontally in west direction, then as in other direction south or north we cannot apply the principal of momentum conservation.

Yvette hangs a 2.4kg bird feeder in the middle of a rope tied between two trees, the feeder creates a
kicyunya [14]

Answer:

a) 0.049 m

b) Yes, increase

Explanation:

Draw a free body diagram.

In the y direction, there are three forces acting on the feeder.  Two vertical components of the tension forces in each rope pulling up, and weight force pulling down.

Apply Newton's second law to the feeder in the y direction.

∑F = ma

2Ty − mg = 0

Ty = mg/2

Let's say the distance the rope sags is d.  The trees are 4m apart, so the feeder is 2m horizontally from either tree.  Using Pythagorean theorem, we can find the length of the rope on either side:

L² = 2² + d²

L = √(4 + d²)

Using similar triangles, we can write a proportion using the forces and distances.

Ty / T = d / L

Substitute:

(mg/2) / T = d / √(4 + d²)

Solve for d:

Td = mg/2 √(4 + d²)

T² d² = (mg/2)² (4 + d²)

T² d² = (mg)² + (mg/2)² d²

(T² − (mg/2)²) d² = (mg)²

d² = (mg)² / (T² − (mg/2)²)

d = mg / √(T² − (mg/2)²)

Given m = 2.4 kg and T = 480 N:

d = (2.4) (9.8) / √(480² − (2.4×9.8/2)²)

d = 0.049 m

b) If a bird lands on a feeder, this will increase the tension in the rope to support the bird's weight.

A rocket burns fuel at a rate of 199 kg/s and exhausts the gas at a relative speed of 9 km/s. Find the thrust of the rocket. Ans
andreyandreev [35.5K]

Answer:

1.791 MN

Explanation:

Thrust of the rocket can be found using the relation

T = v.dm/dt, where

T = thrust off the rocket

v = speed of the rocket, 9 km/s = 9000 m/s

dm/dt = rate at which fuel burns, 199 kg/s

Substituting the values into the formula, we have

T = 9000 * 199

T = 1791000 N

T = 1.791*10^6 N

Since 1 MN = 10^6, thus

T = 1.791 MN
