A truck moving at 20 mph shoots a soccer ball at 20 mph in the opposite direction. How fast is the soccer ball moving? Explain
Brrunno [24]

Answer:

Speed of the soccer ball with respect to ground is ZERO

Explanation:

As we know that truck is moving with speed 20 mph

Now a soccer ball is shoot from truck with respect to the motion of truck in opposite direction

The relative speed of the soccer ball is

v_{bt} = 20 mph

now we know that

v_{bt} = v_b - v_t

so we have

-20 mph = v_b - 20

so we have

v_b = 0

Answer: A = 0.02 m²

Explanation: Solution:

Pressure is expressed in the formula:

P = F / A       where F = mg

  = mg /A

Which wave, A or B, has lower energy? A, because it has a higher amplitude B, because it has a higher amplitude A, because it ha
frutty [35]

Energy of wave depends on its amplitude and it is given as

E = \frac{1}{2} kA^2

here k = constant

A = amplitude

so energy will increase or decrease depends on the amplitude of the wave

So here if we need to check which wave has lower energy then we need to compare the amplitude.

If the amplitude is less then energy must be less

So please check in the figure that which wave out of A and B has lesser amplitude to find out the wave of lesser energy
