![]() ![]() Distance: The sun is located approximately 26,000 light-years away from the galactic center. ![]() The sun is not falling into the supermassive black hole at the galactic center because of the following reasons:ġ. If the galactic center is now thought to contain a supermassive black hole, is the sun not falling into it under the black hole's extreme gravity To know more about friction force visit:-ĭetails : a baseball player of mass of 84.0 kg running at 6.70 m/s slides into Hence, average friction force is exerted on the player is 751.2 N Principle: the laws of friction.Īvg acceleration = f. The average friction force is therefore zero. The person's beginning velocity was zero, and after travelling a distance of 1 km, they returned to that initial velocity. The force applied by an item travelling over a specific period of time at a defined rate of speed is known as the average force. How much friction does a person typically experience? ![]() The average friction force is exerted on the player of mass of 84.0 kg running at 6.70 m/s slides into home plate. The result of dividing each part of the displacement by 42 is (25/42)i + (31/42)j + (7/42)k. Using the Pythagorean theorem, we can calculate the size of the resulting displacement, which equals sqrt(25 2 + 31 2 + 7 2) = 42 cm.Ģb) We can divide the resultant displacement vector by its magnitude to determine the unit vector in the direction of the resulting displacement. R = 2C + B, and for the unit vector multiplying both sides by the magnitude of 2C + B.Ģa) We can easily add the respective components of the three supplied displacements to determine the components of the resultant displacement. The three vectors' sum is therefore (8 + 2 - 2) mi + (6 - 3 - 3) mj + (-2) mk, which may be written as 6mi + 0mj + 2mk.ġc) We can rearrange the preceding equation 2C + B R = 0 to isolate R and determine the unit vector in the direction of R. In the x and y directions, B has components of 2 and -3, respectively. a)25i + 31j + 7k cm, with magnitude 42 cm and b) Unit vector in direction of resultant displacement is (5/14)i + (31/70)j + (3/10)k.ġa) Using Pythagoras theorem, the magnitude of vector A will be found, The magnitude of A is equal to the square root of (4 + 3), which equals 5, and the sides of the right triangle in this circumstance are 4 and 3.ġb) We may simply add the components of the vectors 2A, B, and -C to determine their sum. ![]()
