Answer:
The horizontal component of her velocity is approximately 1.389 m/s
The vertical component of her velocity is approximately 7.878 m/s
Explanation:
The given question parameters are;
The initial velocity with which Margaret leaps, v = 8.0 m/s
The angle to the horizontal with which she jumps, θ = 80° to the horizontal
The horizontal component of her velocity, vₓ = v × cos(θ)
∴ vₓ = 8.0 × cos(80°) ≈ 1.389 
The horizontal component of her velocity, vₓ ≈ 1.389 m/s
The vertical component of her velocity,  = v × sin(θ)
 = v × sin(θ)
∴  = 8.0 × sin(80°) ≈ 7.878
 = 8.0 × sin(80°) ≈ 7.878
The vertical component of her velocity,  ≈ 7.878 m/s.
 ≈ 7.878 m/s.

Theoretically, if the objects have the same mass and are moving towards each other at a speed of 

, after a perfectly elastic collision, the object A is supposed to move with the same velocity in the opposite direction.
