The only force acting on a 2.5 kg canister that is moving in an xy plane has a magnitude of 3.0 n. the canister initially has a velocity of 2.3 m/s in the positive x direction, and some time later has a velocity of 6.4 m/s in the positive y direction. how much work is done on the canister by the 3.0 n force during this time?

44.58 J

Explanation:

mass of block

Force magnitude=3 N

Initial velocity =

Final velocity=

Initial Kinetic Energy=

=

Final Kinetic Energy=

=

Work Done =Final -Initial Kinetic energy=51.2-6.612=44.58 J

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever
