Concrete Barriers

These concrete barriers will stop vehicles, even trucks. Here are the vital statistics: Truck weight = 32 tons. Speed = 50 mph. Kinetic Energy = 5.5 MILLION ft. lbs. Stopped dead in 24 inches!

Somebody is practicing physics without a license...

1. ft-lbs is a measure of torque, not energy.

2. Nebraska is right. The truck isn't 32 tons. Maaaaybe 32,000lbs. Even that seems high.
