You and a friend try to move a 50.0 kg box over a smooth floor (no friction). you push down and right with a force 30.0 n, at angle of 20 degrees below the horizontal. your friend ties a rope to the front of the box and pulls with a 25.0 n force, at an angle 30 degrees above the horizontal. what is the acceleration of the box in the horizontal direction? assuming the box does not move in the vertical direction, what is the normal force on the box?

Explanation:

 Forces in horizontal direction will move the block

30N cos component and 25 cos component will accelerate block

30cos20+25cos30=50a

21.65+28.19=50a

The horse latitudes-high-pressure zones about 30 degrees north and 30 degrees south of the equator.-warm air traveling away from the equator cools and sinks-weather tends to be clear and drythe doldrums-low-pressure near equator-air rises and spreads out toward the poles-rising moist air produces clouds and heavy rainthe westerlies-blow from the west-move from the horse latitudes toward the poles.-bring storms across much of the united statesthe tradewinds-blow from the east-move from the horse latitudes toward the equator  -strong, steady winds
