If the speed of a particle triples ,by what factor does its kinetic energy increase?

The rocket is fired vertically and tracked by the radar station shown. when θ reaches 66°, other corresponding measurements give the values r = 32700 ft, r¨ = 85 ft/sec2, and θ˙ = 0.019 rad/sec. calculate the magnitudes of the velocity and acceleration of the rocket at this position.

What is the relationship between wavelength of light and the quantity of energy per photon?
