A spring-loaded ejector seat launches a 65 kg pilot out of an airplane, which flies horizontally at 98 m/s. The spring is compressed by 1.2 m, and has a constant of 3100 N/m. If the plane's initial altitude was 770 m, how fast is the pilot travelling when he has fallen to a height of 340 m?

G.P.E = mgh = 0.2 * 10 * 100 = 200 J
Now we'll calculate the temperature rise
Q = m * c * (t2 - t1)
Q/(m * c) = t2-t1
t2 = Q/(m * c) + t1 = 200/(0.2 * 400) + 0 = 2.5 C
