According to Guinness, the tallest man to have ever lived was Robert Pershing Wadlow of Alton, Illinois. He was last measured in 1940 to be 2.72 meters tall (8 feet, 11 inches). Determine the speed which a quarter would have reached before contact with the ground if dropped from rest from the top of his head.

Answer:
7.30523 m/s
Explanation:
t = Time taken
u = Initial velocity = 0
v = Final velocity
s = Displacement = 2.72 m
g =  Acceleration due to gravity  = 9.81 m / s 2 = a
Equation of motion
v 2 u 2 = 2 a s v = 2 a s + u 2 v = 2 × 9.81 × 2.72 + 0 2 v = 7.30523   m / s
The speed which a quarter would have reached before contact with the ground is 7.30523 m / s

A majorette in a parade is performing some acrobatic twirlingsof her baton. Assume that the baton is a uniform rod of mass 0.120 kg and length 80.0 cm. 
With a skillful move, the majorette changes the rotation ofher baton so that now it is spinning about an axis passing throughits end at the same angular velocity 3.00 rad/s as before. What is the new angularmomentum of the rod?

Why can one observe an electronic transition of the 3s state to the 3p state in the emission spectrum of the nitrogen atom, but not in its absorption spectrum?
I know that the selection rules technically don't forbid either one since Δ = ± 1 is permitted.

Suppose ϕ ( x ) a scalar field, v μ a 4-vector. According to my notes a quantity of form v μ μ ϕ ( x ) will not be Lorentz invariant.
But explicitly doing the active transformation the quantity becomes
Λ ν μ v ν ( Λ 1 ) μ ρ ρ ϕ ( y ) = v ν ν ϕ ( y )
where y = Λ 1 x and the partial differentiation is w.r.t. y. This seems to suggest that the quantity is a Lorentz scalar, so could be used to construct a Lorentz invariant first order equation of motion.
I'm clearly making a mistake here. But I don't see what I've done wrong. Am I wrong to think that v transforms nontrivially under the active transformation?

In physics problems, the earth is usually considered to be an inertial frame. The earth has a gravitational field and the second postulate of the general theory of relativity says:
"In the vicinity of any point, a gravitational field is equivalent to an accelerated frame of reference in gravity-free space (the principle of equivalence)."
Does this mean that accelerating frames of reference can be inertial?
