How to find when the particle changes direction?

1 answer:

5 0

<span>As time increases, if the particle's velocity changes sign from positive to negative, or negative to positive, then it must have changed (opposite) direction on its linear path. As time increases on a graph of the particle's position versus time, it changes directions when position changes from increasing to decreasing, or from decreasing to increasing.</span>

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

$v_b = 0$
