Answer:
Their translational kinetic energies are the same
Explanation:
The translational kinetic energy of an object is given by the formula:
Where m = the mass of the object and
v = the linear speed of the object
From the question, it is stated that wheel A has the same mass as wheel B, that is 
Linear speed is also a function of the distance covered. Since both wheels cover the same distance within the same interval, we can conclude that 
Both wheels A and B have equal speed and mass, this means that their translational kinetic energy is the same.
Note that translational kinetic energy is not a function of the radius
Answer:
Linear velocity of a rider in a capsule that is located at the perimeter of the wheel = 0.2355 m/s
Explanation:
Diameter = 135 m
Radius, r = 0.5 x 135 = 67.5 m
It revolves at a constant rate and takes 30 minutes
Period, T = 30 minutes= 1800 s
Linear velocity, v = radius x angular velocity
v = 67.5 x 3.98 x 10⁻³ = 0.2355 m/s
Linear velocity of a rider in a capsule that is located at the perimeter of the wheel = 0.2355 m/s
It's the instantaneous speed. Average speed would take all the different speeds from the whole ride in order to fine the median or middle speed.
First take note that you're figuring 10am and 1pm. Their temperatures are 77 degrees and 83 degrees
To solve subtract 83-77=6
So it rose 6 degrees.
