To compute for the heat, 
needed to be absorbed or released, we need
where
is the mass of the alligator, 
is the change in temperature, and 
is the specific heat of the alligator's body. Plugging in all the information we have,
Recall that 1 Watt = 1 J/s, thus time needed to absorb radiation from the sun is
That means it takes 4250 seconds for the alligator to warm up to be able to absorb the radiation from the sun.
Answer: 4250 seconds

Answer: 4250 seconds
The sprinter is in uniform accelerated motion, and its initial velocity is zero, so the relationship betwen space (S) and time (t) is
where a is the acceleration. Using the data of the problem, we can find a:
So now we can solve the 3 parts of the problem.
a) power output at t=2.0 s
The velocity at t=2.0 s is
the kinetic energy of the sprinter is
and so the power output is
b) power output at t=4.0s
The velocity at t=4.0 s is
the kinetic energy of the sprinter is
and so the power output is
c) Power output at t=6.0 s
The velocity at t=2.0 s is
the kinetic energy of the sprinter is
and so the power output is
where a is the acceleration. Using the data of the problem, we can find a:
