A 92.5 kg stunt man stands on a piston that will launch him out of a vertical tube. The piston applies a constant force F to the man’s feet. Starting from rest, the force is applied as the man moves vertically 3.25 m, and while the piston is pushing, the man attains a velocity of 25.5 m/s. What was the man’s apparent weight during this time interval?
A. 9.3 kN
B. 18.5 kN
C. 19.4 kN
D. 10.2 kN
D. 10.2 kN

One of the first atomic bombs released energy equivalent to that of 20,000 tons of TNT explosive
How much mass was converted to energy by this explosion, given that 1000 tons of TNT produce 4.3 × 1012 J of energy. Incidentally, modern H-bombs have energy yields 1000 times as much! (c = 3.0 × 108 m/s)
