1) A sofa is pushed with a force of 600 N at an angle of 22 degrees to the direction of displacement of that sofa. if it is displaced 4.6 meters, then how much work was done to move the sofa? 2) A crane is used to lift an air conditioner straight to the roof of a building. the building is 35 meters tall. the air conditioner has a mass of 280 kg. how much work is done to lift the air conditioner to the top of the building.
(please show work or an explanation as to how to do it :)

step-by-step explanation:

we are given

we have to simplify it

firstly, we will factor it

now, we can cancel like terms

now, we can combine it

so, we get

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2

the force represented by vector a is normal force. if the hockey puck is moving to the right, when it is hit with a significant force by the hockey stick the puck will move off in a different direction. correct on edge.
