Two deer run toward each other. One deer has a mass of 20 kg and runs west

with a speed of 5 m/s, while the other has a mass of 30 kg and runs east with

a speed of 4 m/s. What is the total momentum of the system made up of the

two deer?

Answer:20 kg·m/s east

Explanation:

Just did it

20 kg. m/s, East

Explanation:

Step 1: identify the given parameters

M₁ = 20kg

V₁ = 5m/s

M₂ = 30kg

V₂ = 4m/s

Total momentum (P) = ?

Step 2: calculate the total momentum (P)

P = ΔMV

P = M₂V₂ - M₁V₁

P = (30*4) - (20*5)

P = 120 - 100

P = 20kg. m/s

The total momentum of the system is 20kg. m/s east in the direction of the second deer.
