Adriver traveling at 29 m / s sees a tree laying in the middle of the road. she brakes to full stop in 4.3 s. calculate the driver's acceleration while stopping (deceleration). (hint: you know the final velocity)

Aforklift raises a 1,020 n crate 3.50 m up to a shelf. how much work is done by the forklift on the crate? the forklift does j of work on the crate.

What is the measure of a change in an objects velocity?

The electric field between square plates of a parallel-plate capacitor has magnitude e. the potential across the plates is maintained with constant voltage by a battery as they are pulled apart to twice their original separation, which is small compared to the dimensions of the plates. the magnitude of the electric field between the plates is now equal to a)e b)e/4 c)e/2 d)4e e)2e
