Answer:
v=1.26 m/s
Θ=81°NE
Explanation:
Linear momentum is the product of the mass and velocity of an object.
Dog's momentum can be hold using its mass and velocity:
m=26.2kg
v=3.21 m/s
(kg⋅m/s)
same thing with the cat
m=5.30kg
v=2.64m/s
(kg⋅m/s)
owner's momentum
p =13.992 m/s i + 84.102 m/s j
divide by mass to get velocity:
v = 0.20m/s i + 1.25 m/s j
mag v = √(0.20² + 1.25²) m/s = 1.26 m/s
Θ = arctan(1.25/0.2) = 81º north of east
