Answer:
0.48 kgm/s
Explanation:
= mass of the particle = 2.43 μg = 2.43 x 10⁻⁶ x 10⁻³ kg = 2.43 x 10⁻⁹ kg
= velocity of the particle = 1.97 x 10⁸ m/s
= momentum of the particle
momentum of the particle is given as
inserting the values
kgm/s
As per Einstein's theory of relativity we know that when an object will move with the speed comparable to the speed of light then the length of the object will be different from its length at rest position
This is also known as length contraction theory
As we know here that
so here we know that
v = 0.95 c
so from above equation we will have
so here the length will be SHORTER
Answer:
24.325 kg m/s
Explanation:
Initial momentum, pi = 18 kg m/s
F = < -4, 12, 0>
t = 0.5 s
Let the final momentum is pf.
The magnitude of force is
According to the Newton's second law, the rate of change of momentum is equal to the force.
pf - 18 = 6.325
pf = 24.325 kg m/s
Thus, the momentum of body after 0.5 s is 24.325 kg m/s.
