A 3.00 kg block moving 2.09 m/s
right hits a 2.22 kg block moving
3.92 m/s left. Afterward, the
3.00 kg block moves 1.11 m/s left.
Find the momentum of the 2.22 kg
block afterwards.

Initially, a particle is moving at 5.33 m/s at an angle of 37.9° above the horizontal. two seconds later, its velocity is 6.11 m/s at an angle of 54.2° below the horizontal. what was the particle's average acceleration during these 2.00 seconds in the x-direction (enter first) and the y-direction?

Consider a hydrogen atom in the ground state. what is the energy of its electron? =e= jj now consider an excited‑state hydrogen atom. what is the energy of the electron in the =5n=5 level? =e5= j
