A 4.00 kg ball is moving at 4.00 m/s to the EAST and a 6.00 kg ball is moving at 3.00 m/s to the NORTH. The total momentum of the system is:.A. 14.2 kg m/s at an angle of 48.4 degrees SOUTH of EAST. B. 48.2 kg m/s at an angle of 24.2 degrees SOUTH of EAST. C. 48.2 kg m/s at an angle of 48.4 degrees NORTH of EAST. D. 24.1 kg m/s at an angle of 24.2 degrees SOUTH of EAST. E. 24.1 kg m/s at an angles of 48.4 degrees NORTH of EAST.

Explanation:

Momentum = mass*velocity of a body

For a 4.00 kg ball is moving at 4.00 m/s to the EAST, its momentum = 4*4 = 16kgm/s

For a 6.00 kg ball is moving at 3.00 m/s to the NORTH;

its momentum = 6*3 = 18kgm/s

Total momentum = The resultant of both momentum

Total momentum = √16²+18²

Total momentum = √580

total momentum = 24.1kgm/s

For the direction:

The total momentum is 24.1 kg m/s at an angle of 48.4 degrees NORTH of EAST

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
