Answer:
a) Bullet will hit
b) Bullets will not hit
Explanation:
Given:
The velocity of the bullet, u = in the rest frame of the bullet pursuit car
The velocity of the original frame of reference, v = with respect to the pursuit car.
Now, according to the Galileo
the velocity of the bullet in the original frame of reference (u') will be
u' = u - v
on substituting the values we get
u' =
or
u' =
or
u' =
since this velocity ( ) is greater than the (
)
hence,
<u>the bullet will hit</u>
Now, according to the Einstein theory
the velocity of the bullet in the original frame of reference (u') will be
on substituting the values we get
or
or
since,
is less than (
), this means that the bullet will not hit
