what are the horizontal and vertical components of a vector that is 25units long with an angle of 130 degrees​

The horizontal component of the vector ≈ -16.06

The vertical component of the vector ≈ 19.15

Explanation:

The magnitude of the vector, = 25 units

The direction of the vector, θ = 130°

Therefore, we have;

The horizontal component of the vector, Rₓ = × cos(θ)

∴ Rₓ = 25 × cos(130°) ≈ -16.06

The horizontal component of the vector, Rₓ ≈ -16.06

The vertical component of the vector, R = × sin(θ)

∴  R = 25 × sin(130°) ≈ 19.15

The vertical component of the vector, R ≈ 19.15

(The vector, R = Rₓ + R

= Rₓ·i + R·j

∴ ≈ -16.07·i + 19.15j)

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
