According to special relativity, in which frames of reference does light in a vacuum travel at less than 3.0 108 m/s?
ch4aika [34]
The correct option is D.
According to special relativity, in no frame of reference does light in a vacuum travel at less than the speed of light, the speed of light in a vacuum is the same for any inertial reference frame.This fact remain valid no matter the speed of a light source relative to another observer.

A paintball is fired horizontally from a tower 45 m above the ground. If the paintball gun fires at 90 m/s… How long does it tak
ankoles [38]

Answer:

The time taken for the paint ball to hit the ground is t =  2.143 \ s

The distance of the landing point from the tower is d = 192.86 \  m

Explanation:

From the question we are told that

   The height of the tower is h =  45 \ m

    The speed of the paintball in the horizontal direction is  v_x =  90 \  m/s

Generally from kinematic equation we have that

      h =  ut + \frac{1}{2} at^2

Here u is the initial  velocity of the paintball in the vertical direction and the value is 0 m/s , this because the ball was fired horizontally

         a is equivalent to g  = 9.8\ m/s^2

        t is the time taken for the paintball to hit the ground

   So    

       45  =  0* t + \frac{1}{2} 9.8 * t^2

=>    t =  2.143 \ s

Generally the distance of its landing position from the tower is

         d = v  *  t

=>      d = 90 *  2.143

=>    d = 192.86 \  m
