Answer: Speed = m/s
Explanation: Like in classical physics, when external net force is zero, relativistic momentum is conserved, i.e.:
Relativistic momentum is calculated as:
p =
where:
m is rest mass
u is velocity relative to an observer
c is light speed, which is constant (c=m/s)
Initial momentum is zero, then:
= 0
= 0
To find speed of the heavier fragment:
<u>The speed of the heavier fragment is </u><u>m/s.</u>
Answer:F=11.76 kN
Explanation:
Given
mass of rocket
Force F is applied up to a height of 100 m then it is shut off
final velocity v up to which force is applied is given by
After this rocket continues to move to a maximum height under the action of gravity
using
thus Force is
<span>Reducing the distance between them. In theory, also increasing the mass; but you can't really change the mass of an object. However, you can compare the forces if you replace an object by a different object, which has a different mass.

i hope this will work..
