The vibrations along a transverse wave move in a direction _________.
GrogVix [38]

Answer: perpendicular to it oscillations.

Explanation: A transverse wave is a wave whose oscillations is perpendicular to the direction of the wave.

By perpendicular, we mean that the wave is oscillating on the vertical axis (y) of a Cartesian plane and the vibration is along the horizontal axis (x) of the plane.

Examples of transverse waves includes wave in a string, water wave and light.

Let us take a wave in a string for example, you tie one end of a string to a fixed point and the other end is free with you holding it.

If you move the rope vertically ( that's up and down) you will notice a kind of wave traveling away from you ( horizontally) to the fixed point.

Since the oscillations is perpendicular to the direction of wave, it is a transverse wave

A 2 kg ball with an initial velocity of 10 m/s moves at an angle 60º above the +x-direction. The ball hits a vertical wall and b
kow [346]

Answer:

I = 20 i ^ N s

Explanation:

For this problem let's use the Impulse equation

       I = Δp = m v_{f}- v₀

The impulse and the velocity are vector quantities, let's calculate on each axis, let's decompose the velocity

     cos 60 = vₓ / v

     vₓ = v cos 60

     sin60 = v_{y} / v

     v_{y} = v sin60

     vₓ = 10 cos 60

     v_{y} = 10 sin60

    vₓ = 5.0 m / s

    v_{y} = 8.66 m / s

Let's calculate the impulse on each axis

X axis

     Iₓ = m v_{xf} - m vₓ₀

How the ball bounces

    v_{xf} = - vₓ₀ = vₓ

    Iₓ = 2 m vₓ

    Iₓ = 2 2 5

    Iₓ = 20 N s

Y axis

   I_{y} = m v_{yf} - m vyo

On the axis and the ball does not change direction so

   v_{yf} = vyo

  I_{y} = 0

The total momentum is

   I = Iₓ i ^ + I_{y} j ^

   I = 20 i ^ N s
