Momentum And Collisions 2

Question

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 4.00 106 m/s

kg·m/s

(b) a 17.5 g bullet moving with a speed of 265 m/s

kg·m/s

(c) a 71.0 kg sprinter running with a speed of 10.5 m/s

kg·m/s

(d) the Earth (mass = 5.98 1024 kg) moving with an orbital speed equal to 2.98 104 m/s.

kg·m/s

Answer 1

Hi Dominic!

 

Linear momentum, in each case, is just the product of mass and velocity.  That should answer each of the questions above, but let me know if you have any further questions about this.
