A floating ice block is pushed through a displacement vector d= (15 m)i - (12 m)j along a straight embankment by rushing water, which exerts a force vector F = (210 N)i - (150 N)j on the block. How much work does the force do on the block during thedisplacement?

explanation:

a fuel engine ( known as a gasoline engine in american english )is an internal combustion engine with spark ignition, designed to run on petrol (gasoline) and similar volatile fuels.

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
