Answer:
Part a)
Part b)
So density of atmosphere at Martian Surface is very less than the density at Earth.
Explanation:
Part a)
As per ideal gas equation we know that
here we know that Martian atmosphere is equivalent to that of carbon
so we will have
now we will have
Part b)
Now for the earth surface the density of air is given for
so we will have
So density of atmosphere at Martian Surface is very less than the density at Earth.

a)
b)
Explanation:
a) Final angular velocity
:
Before solving this part, we have to stay clear that the angular momentum is conserved, since we are dealing with circular motion, then:
Hence:
(1)
Where:
is the initial moment of inertia of the system
is the initial angular velocity
is the final moment of inertia of the system
is the final angular velocity
But first, we have to find and :
(2)
(3)
Where:
is the student's moment of inertia
is the mass of each object
is the initial radius
is the final radius
Then:
(4)
(5)
Substituting the results of (4) and (5) in (1):
(6)
Finding :
(7) This is the final angular speed
b) Change in kinetic energy:
The rotational kinetic energy is defined as:
(8)
And the change in kinetic energy is:
(9)
Since we already calculated these values, we can solve (9):
(10)
Finally:
This is the change in kinetic energy
Answer:
Explanation:
Sum moments about the rear tires to zero to find the force on the front tires
F[3.13] - 1540(9.81)[3.13 - 1.09] = 0
F = 9,846
so each front wheel supports half of that weight
F/2 = 9846/2 = 4,923 ≈ 4920 N
Sum vertical forces to zero
9,846 + R - 1540(9.81) = 0
R = 5,261
so each rear wheel supports half of that weight
R/2 = 5261/2 = 2630.52 ≈ 2630 N
