Linear momentum

$\overline{){\mathit{p}}{\mathbf{=}}{\mathit{m}}{\mathit{v}}}$, where m is mass and v is velocity.

**(a)**

m = 1.67 × 10^{-27} kg

v = 5.45 × 10^{6}m/s

Calculate the magnitude of the linear momentum for the following cases.

(a) a proton with mass 1.67 × 10^{-27} kg, moving with a speed of 5.45 × 10^{6}m/s.

(b) a 16.0-g bullet moving with a speed of 435 m/s

(c) a 72.5-kg sprinter running with a speed of 11.0 m/s

(d) the Earth (mass = 5.98 × 10^{24} kg) moving with an orbital speed equal to 2.98 × 10^{4} m/s.
