Calculate the magnitude of the linear momentum for thefollowing cases:
a) a proton with mass 1.67 x 10-27 kg, moving with a speed of 5.00 x106 m/s
b) a 15.0-g bullet moving with a speed of 300 m/s
c) a 75.0-kg sprinter running with a speed of 10.0 m/s
d) Earth (mass = 5.98 x 1024 kg) moving with anorbital speed equal to 2.98 x 104 m/s.
