In a crash test, a 2,500 kg car hits a concrete barrier at 1.3 m/s2. Calculate the amount of force at which the car strikes the barrier.
The car strikes the barrier with a force of N.

altitude, density, pressure

air gets less dense the higher the altitude and also the air pressure is less as altitude rises.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
