Aworker pushes a large rock to the north while another worker by pushing it to the east. if they both exert equal force, in what direction does the rock move? question 2 options: northeast east north southwest

let the magnitude of force applied by each worker be "F"

consider east-west direction along X-axis and north-south direction along Y-axis

In unit vector form, force vector by worker pushing in east direction is given as

= F + 0  

In unit vector form, force vector by worker pushing in north direction is given as

= 0 + F  

resultant force is given as the vector sum of two vector forces as

= +

= (F + 0   ) + (0 + F   )

= F +  F  

direction of the force is hence given as

θ = tan⁻¹(F/F)

θ =  tan⁻¹(1)

θ = 45 degree north of east

hence the direction is north-east

write a paragraph or story to explain the transformation between potential and kinetic energy as shown in your picture or model.  

you should have at least 5 complete sentences with a main idea and supporting details.  

you must include the following words:  

potential energy

kinetic energy

mechanical energy

conservation of energy

dude, this is hard lol : ))
