URGENT ASAP The driver of a 1000 kg car is speeding. He loses control and collides with a wall. The car comes to rest from a speed of 40 m/s. The crumple zone of the car absorbed 80 kN of force. How long did it take for the car to come to rest?

How does the entropy of steam compare to the entropy of ice?

It may seem strange that the selected velocity does not depend on either the mass or the charge of the particle. (for example, would the velocity of a neutral particle be selected by passage through this device? ) the explanation of this is that the mass and the charge control the resolution of the device--particles with the wrong velocity will be accelerated away from the straight line and will not pass through the exit slit. if the acceleration depends strongly on the velocity, then particles with just slightly wrong velocities will feel a substantial transverse acceleration and will not exit the selector. because the acc
