hi,

im not sure how to do this question 80 N and 60 N force act concurrently on a point. find magnitude of the vector sum if the forces pull -in the same direction -in opposite direct. -at right angles to each other thanks

is this right? a 50kg barbell can be lifted by usinga force of 180 N. what is the force of gravity on this planet? if the same barbell is lifted on earth, what minimal force is needed? -i got 3.6 for gravity of the unnamed planet; and 49 N for the minimal...

80 N and 60 N force act concurrently on a point. find magnitude of the vector sum if the forces pull -in the same direction -in opposite direct. -at right angles to each other seriously, i don't understand what you are supposed to do

im not completely sure im right with this question a lawn spreader is pushed across a lawn by applying a force of 95N along the handle that makes an angle 60 degrees with the horizontal. a- what is the horiz. and vert. comp. of the force. b- when the hand...

not that hard... its y=mx +b so, 4=-2(0) +b therfore, b = 4, so, y= -2x +4

i don't understand.. do u use cos and sin? i don't understand the question.

notation is when u don't want to write out the whole thing, its a shorter way of writing certain numbers
