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

Respuesta :

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

[tex]v_{bt} = 20 mph[/tex]

now we know that

[tex]v_{bt} = v_b - v_t[/tex]

so we have

[tex]-20 mph = v_b - 20[/tex]

so we have

[tex]v_b = 0[/tex]
