Answer:
The time interval is 22.76 hr.
Explanation:
Given that,
Time = 30 hrs
Speed = 0.74c
We need to calculate the time interval measured in earth frame
Using formula of time dilation
Where, = time interval measured in earth frame
=proper time interval
Put the value into the formula
We need to calculate the proper time interval when the velocity is 0.86c
Using formula of time dilation
Hence, The time interval is 22.76 hr.

Answer:
The answer is 312.5j
Explanation:
The kinetic energy (KE):
KE=1/2*m*v^2
M= mass of the object
v= velocity of the object
We have;
m=25g
v=5m/s
KE=1/2*25g*5^2m/s
KE =312.5j
