a) A 1795 kg hippopotamus is running towards a hunter at a speed of 2.75 m/s.

Calculate the momentum of the hippo. Show all work.

• 1.79 x 10^3 kgm/s
• 6.53 x 10^2 kgm/s
• 6.40 x 10^3 kgm/s
• 4.94 x 10^3 kgm/s

b) How many times larger is the momentum of the 1795 kg hippo than the momentum of a 50.8 g dart being fired at 405 m/s?

• 0.240 times
• 240 times
• 31.7 times
• 86.9 times

c) What is the momentum of the 81.5 kg hunter running along the riverside path, at 4.05m/s, after missing the 1795 kg hippo, with the dart?

• 3.24 x 10^3 kgm/s
• 3.30 x 10^-1 kgm/s
• 330 kgm/s
• 760 kgm/s
