Kinetic energy is equal to one half the mass times the velocity squared. Thus in this case it would be 0.5 * 1600kg * 12.52 (m/s)2 = 800*156.25 kg m2/s2 = 125000 kg m2/s2 = 125000 N m = 125000 J = 125 kJ
v = square root of 1200/0.01
Remember : Force = kg * m*s^-2 Momentum = kg * m* s^-1 The difference is force involves acceleration,; the difference in speec(velocity) over a given timr. Momentum involves speed (velocity) only. NOT a change in velocity. So your van of 1200 kg with a speed pf 25 ms^-2 The momentum is = 1200 kg & 25 ms^-2 = 30,000 kg m s^-1
1200 pounds = 544.310844 kilograms
1200ml = 1200 cm3 unless the rock floats (there are rocks that have density less than 1) in which case the volume of the rock is greater than 1200 cm3 and the mass is 1200 g
It's clearly got a lot of kinetic energy, but if the car is on an elevated freeway, it also has some potential energy. The kinetic energy can be calculated as E=1/2*mv2, or one-half of the mass times velocity squared. So .5*1200*10000=6,000,000 Joules of energy.
The formula for kinetic energy is MV2/2 where M is the mass of the object and V is the velocity of the object. Since the vehicles have the same speed, the only thing changing in your question is the mass of the vehicles. Therefore the SUV has twice the mass of the car, thus twice the kinetic energy.
Kinetic energy is equal to one half the mass times the velocity squared. Thus in this case it would be 0.5 * 1600kg * 12.52 (m/s)2 = 800*156.25 kg m2/s2 = 125000 kg m2/s2 = 125000 N m = 125000 J = 125 kJ

Velocity means speed. So high velocity is high speed and low velocity is low speed. Example: High velocity 204 Ruger 32 grains 4000 fps 1200 ft. lbs. Low velocity 577 Nitro Express 750 grains 2050 fps 7000 ft. lbs.
All you must do here is multiply the 1200 km by the number of hours, here 2.5. The plane went 3000 km.

80 meters. Since the only force on the car is centripetal force then:Fc = macac = v2/rFc = (mv2)/rSolve for rr = (mv2)/Fcr = (1200)(20)2/(6000)r = 80m(See my work in the link below.)
v = square root of 1200/0.01
1 slab of 1200 metres x 450 metres will certainly cover 1600 square metres. You may have trouble moving it into position, though.
