Answer:
The relativistic speed of a particle is 
Explanation:
Given that,
Time = 6 sec
Force = 1
Mass of the particle 
We need to calculate the acceleration
Using formula of acceleration

Put the value into the formula


We need to calculate the velocity after 6 sec
Using equation of motion

Put the value


The velocity in term of c



Hence, The relativistic speed of a particle is
Answer:
Restoring force of the spring is 50 N.
Explanation:
Given that,
Spring constant of the spring, k = 100 N/m
Stretching in the spring, x = 0.5 m
We need to find the restoring force of the spring. It can be calculated using Hooke's law as "the force on a spring varies directly with the distance that it is stretched".


F = 50 N
So, the restoring force of the spring is 50 N. Hence, this is the required solution.
The intersection of logic and ethics concerns questions about the nature of moral reasoning. ... If one can successfully carry out such deductions, then moral reasoning is guided properly by consideration of nonmoral facts from which moral conclusions can be derived.
Answer:
0.29713 m/s
Explanation:
m = Mass of person
g = Acceleration due to gravity = 9.81 m/s²
v = Velocity
r = Radius = 18 mm
By balancing the forces in the system we have

The velocity of the coaster is 0.29713 m/s
If you look at the units of density, g/cm^3 you will see it's grams divided by volume (cm^3).
218.9 g / (0.5*1.55*25 cm^3) = 11.3 g/cm^3
