Question

For this assignment, you submit answers by question parts. The number of submissions remaining for each question part only changes if you submit or change the answer. Your last submission is used for your score. Calculate the magnitude of the linear momentum for the following cases. (a) a proton with mass 1.67 times 10^-27 kg, moving with a speed of 4.35 times 10^6 m/s kg middot m/s (b) a 13.5-g bullet moving with a speed of 455 m/s kg middot m/s (c) a 71.0-kg sprinter running with a speed of 10.5 m/s kgmiddotmiddot m/s (d) the Earth (mass = 5.98 times 10^24 kg) moving with an orbital speed equal to 2.98 times 10^4 m/s. kg middot m/s

Explanation / Answer

p = mv

a) p = 1.67*10^-27 * 4.35*10^6 = 7.2645*10^-21 kg*m/s

b) p = 0.0135*455 = 6.1425 kg*m/s

c) p = 71*10.5 = 745.5 kg*m/s

d) p = 5.98*10^24*2.98*10^4 = 1.782*10^29 kg*m/s
