Two ice skaters, each with a mass of 72.0 kg, are skating at 6.45 m/s when they collide and stick together. if the angle between their initial directions was 121°, determine the components of their combined velocity (in m/s) after the collision. (let the initial motion of skater 1 be in the positive x-direction and the initial motion of skater 2 be at an angle of 121° measured counterclockwise from the positive x-axis.)
the bal will not change its velocity.
about 45° and at the middel
well, their are quite a few differences !
first difference is a main sequence star is made of carbon, while a neutron star is made of neutrons. another difference is a main sequence star still has hydrogen to burn, while a neutron star is a remnant of a supernova.
a main sequence star is what’s left over from a low-mass star death, while a neutron star is what’s left from the death of a high-mass star. main sequence star and a neutron star are considered the same thing, except a main sequence star spins.
