A cart is pulled 5 m up a ramp under a constant force of 40 N. The ramp is inclined at an angle of 30 degrees. How much work is done pulling the cart up the ramp ?
could you give me the formula for finding work?
i did this in grade 8 and don't exactly remember :P
:O this is a grade 12 calculus question ! @helpsos
work = force over a distance W = F*Dx F = 40N |dw:1362369200410:dw| find the x component of the distance he travels. this is Dx. then just plug it into the work equation.
how do you get 60 degrees ?
|dw:1362370304112:dw|
30+60+90 = 180 its a right triangle.
how did you determine the 30 degrees ? @tomo
