40 m/s
The momentum of the spaceship is given by the product of its mass and velocity. Therefore, the velocity can be calculated by dividing the momentum by the mass of the spaceship. In this case, the magnitude of the velocity is 40 m/s to the left.
To calculate the magnitude of the spaceship's velocity, you would divide the momentum by the spaceship's mass. In this case, 20000 kg·m/s / 500 kg = 40 m/s. Therefore, the spaceship's velocity has a magnitude of 40 m/s to the left.
The momentum of the car is calculated by multiplying its mass (20000 kg) by its velocity (15 m/s). Therefore, the momentum of the car is 300,000 kg m/s.
The initial momentum of the railroad car is 120,000 kgm/s (20,000 kg * 6 m/s). When the 8000 kg load of gravel is dropped in, the total momentum is conserved. Therefore, the final speed of the railroad car can be calculated by dividing the total momentum (120,000 kgm/s) by the new total mass (28,000 kg). This gives a final speed of 4.29 m/s.
There are approximately 44.092 pounds in 20000 grams.

Kinectic energy is the same as potential energy - so 20000 is the sames as half x m x vsquared - therefore 20000 is half 250 which is 125 - 20000 divided by 125 is velocity squared so then square root your answer and there it is
This star would be a white dwarf, as it has a high surface temperature of 20000 K but a low absolute magnitude of 10. White dwarfs are small, dense remnants of low to medium mass stars that have exhausted their nuclear fuel and collapsed.
There are only one significant figure in the number 20000. Significant figures are the digits in a number that carry meaning contributing to its precision. In this case, the zeros in 20000 are not considered significant because they are serving as placeholders to indicate the magnitude of the number rather than its precision.
Best way is visual and constant mass. KE = 1/2 mV2 KE = 1/2(100 kg)(20 m/s)2 = 20000 joules ================== 80000/20000 = 4 times the kinetic energy by doubling the velocity because the velocity is squared --------------------------------------------------------------------------------------------------
