US 120mm Sabot (1984): 9.8 MJ RU 125mm Sabot (1972): 6.1 MJ 1 kg of TNT: 4.184 MJ GE 88mm L56 Flak: 2.8 MJ Ford Explorer at 60 MPH: 0.66 MJ Mike Tyson Punch: 0.0016 MJ (1600 J)
In all cases, the variables are:
EK: Kinetic Energy (joules) M: Mass (kilograms) V: Velocity (m/sec)
In the case of closing collisions (i.e. a plane traveling at 300 m/s towards another plane also traveling towards the other plane at 150 m/s), add both velocities to each other. In our prior example, the total velocity would be 300 + 150 = 450 m/s.
The most common use of closing collisions is an ABM interceptor striking an incoming warhead -- some common values for this are:
GBI EKV: 64 kg at about 8 km/sec. SM-3 Kinetic Warhead (aka KV):16.78~ kg at about 4.5 km/sec.
Common Ballistic Missile Velocities are:
IRBM (1500 Miles / 2400 km): 4.4~ km/sec. ICBM (5000 miles / 8000 km): 8~ km/sec.
To simplify inputting values, I've chosen to use kilojoules (KJ) for Kinetic Energy input to reduce the number of zeroes.
Remember 1000 J = 1 KJ and 1000 KJ = 1 MJ.
