Answer:
As speed of a particle has a limit so does its momentum has a limit.
Explanation:
As we know that in this Universe no information can travel faster than the speed of light.
The speed of light is the fastest possible speed and hence the quantities dependent on it also have certain limits.
The momentum of a body at normal non-relativistic speed is given as:
The momentum of a body at relativistic speed (a speed of the order of speed of light) is given as:

Answer:
5123.79 kg
Explaination:
I did 5,123,788 divided by 1000 and got 5123.788
Then I rounded to the nearest 10th place.
Hope this helps, have a great day!

Answer:
Explanation:
mass, m = 50 g
moment of inertia, I = 9 x 106-5 kg m^2
radius, r = 0.7 cm
(a) As it moving downwards
Let T be the tension in the string
T = m (g + a) .... (1)
where, a be the acceleration
τ = I α = T r
α = a / r
So, I x a / r = T x r
a = T r^2 / I
Substitute in equation (1) we get
a = m (g + a) r^2 / I
a = mgr^2 / (I - mr^2)
a = 0.050 x 9.8 x 0.007 x 0.007 / (9 x 10^-5 - 0.050 x 0.007 x 0.007)
a = 2.401 x 10^-5 / (87.55 x 10^-6)
a = 0.274 m/s^2
τ = I x α = I x a / r
τ = 9 x 10^-5 x 0.274 / 0.007
τ = 3.52 x 10^-3 Nm
(b) α = a / r
α = 0.274 / 0.007 = 39.14 rad/s^2
