Newtons third law (inertia) is to blame
I think it false. Sorry if i'm wrong.
Answer:

Explanation:
Uncertainty principle say that the position and momentum can not be measured simultaneously except one relation which is described below,

Given that the uncertainty in x is 0.1 mm.
Therefore,

Therefore, uncertainty in the transverse momentum of photon is 
Answer: 7200 m
Explanation: The solution is, first convert 15 minutes to seconds.
15 mins x 60 s / 1 min = 900 s
Use the formula for speed which is v= d/t then derive for d.
d = vt
= 8 m/s ( 900s)
= 7200 m
