22. || In a crash test, a car is driven into a solid wall at a speed of 35 mph. Figure P4.22 shows the car's acceleration as it crashes into the wall. What is the maximum force experienced by the 1650 kg car? a (m/s²) 300 200 100 0- 0 50 100 150 - t (ms) 200

An object falls from a high building.  What will its velocity be after 7 seconds of falling?  An object falls from a high building and hits the ground in 9.5 seconds.  What is the height of the building? During a storm, a piece of metal was knocked off a building.  The metal fell a distance of 300 meters to the ground. How long did it take the metal to hit the ground? What will the velocity of the metal be when it hits the ground? An object falls from the Burj Khalifa (located in United Arab Emirates) and takes 13 seconds to hit the ground.     What is its velocity at impact?   How tall is the building? What is the object’s acceleration at the 3rd second? What is the object’s acceleration at the 7th second? If the Burj Khalifa were actually 2000 meters tall, how long would an object take to fall from the top of the building to the ground? A cartoon coyote (who is it?) drops an anvil off a cliff to try to catch a bird (who is it?).…

What is the acceleration at 8.2 s?

A rock is ejected from a volcano with an inital velocity of 43.8 m/s. How high will the rock reach before falling down? Air resistance doesn't have an effect.
