(a) Suppose the speed of light were only 3000 m/s. A jet fighter moving toward a target on the ground at 800 m/s shoots bullets, each having a muzzle velocity of 1000 m/s. What are the bullets' velocity relative to the target? (b) If the speed of light was this small, would you observe relativistic effects in everyday life? Discuss.

To determine

(a)

The speed of the bullets relative to the target.

Explanation

Given info:

• The jet fighter moving towards the target is 800ms-1 .
• The muzzle velocities of the bullets are. .
• The speed of the light is 3000ms-1 .

Formula used:

Formula to find the bullets speed relative to the target is

u=v+u'1+vu'c2

Here, u is the bullets speed relative to the target is, v velocity of the jet fighter, u' is the muzzle velocities of the bullets and c is the speed of light

To determine

(b)

If the speed of light is small than do, we notice relativistic effect.
