The brightest, hottest, and biggest stars are the brilliant blue stars designated as spectral class O. As is the case of all stars, class O stars move with speeds that are measured in km/s. If a class O star moves with a speed of 255 km/s and has a momentum of 8.62 × 10^36 kg • m/s, what is the star’s mass?

Which of these questions might a character ask if the conflict is man versus self? a. which path should i take to better myself? b. which boulder will be too heavy for me to carry? c. which friend is going to ditch me today? d. all of the above
