Determine the mass of a truck that slows from 32.7m/s to 15.9m/s in 4.31s if the brakes apply an average net force of 8780N?

Two objects of different mass start from rest, are pulled by the same magnitude net force, and are moved through the same distance. the work done on object 1 is 900 j. after the force has pulled each object, object 1 moves twice as fast as object 2. how much work is done on object 2?

Where is the potential energy throughout the loading, cocking, and releasing of the trebuchet?

1. a camcorder has a power rating of 19 watts. if the output voltage from its battery is 7 volts, what current does it use?answer units 2. a 1.5m wire carries a 6 a current when a potential difference of 57 v is applied. what is the resistance of the wire? your
