Density = mass divided by volume.So, the mass = density times volume.mass = 1.29 x 1 kglinear momentum is defined as mass times velocityso the linear momentum of a cubic metre at 15,000 m per hour would be 1.29 x 15km/h. The units would be kg km/h, which are not the SI units. These are kg m/s. To get to them the speed has to be converted into metres per second.

The mass of proton is given by
Energy of proton is given by
Energy of electron is given by
Divide the equations
The particle will be 1833 times the less energetic particle
337.7 m/s
Explanation:
1520 m/s ÷ 4.5s = 337.7 m/s
