Adriver speeds along a curved road and sees a fallen tree on the road. he applies the brakes but is unable to stop in time. when the car hits the tree, it slows down from 6 meters/second to 0 meters/second. what was the change in velocity during this time? the change in velocity during the collision was   meters/second. need it fast

The change in velocity is the difference of the final velocity and the initial velocity:

0 – 6 = -6 m/s.

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray
