A car's bumper is designed to withstand a 4.32 km/h (1.2-m/s) collision with an immovable object without damage to the body of the car. The bumper cushions the shock by absorbing the force over a distance. Calculate the magnitude of the average force on a bumper that collapses 0.270 m while bringing a 950 kg car to rest from an initial speed of 1.2 m/s.

Groups of organs that work together to complete a process in the body are called: a. cells b. tissues c. nerves d. systems

You are traveling in a car going at a constant speed of 100km/h down a long, straight highway. you pass another car going in the same direction which is traveling at a constant speed of 80km/h. as measured from your car's reference frame this other car is traveling at −20km/h. what is the acceleration of your car as measured from the other car's reference frame? what is the acceleration of the other car as measured from your car's reference frame?

What is a good example of instantaneous speed
