Question

a force of 591lb is required to pull a boat up a ramp inclined at 17.0 degreee with the horizontal how much does the boat weight help me plz satellite73 plzzz

Answer 1

i got 618 for the answer

Answer 2

i have no idea how to do this
did the link not help?

Answer 3

ya but its showe me that i got 618 i did the same way that they did

Answer 4

did you draw a free body diagram? and 618 what?

Answer 5

Answer 6

is the answer

Answer 7

i dont no how to

Answer 8

ya and how do i solve it now

Answer 9

sir plz help me i been trying this for 2 hours

Answer 10

\[Fn=fg(cosx)\]
sorry i forgot to include the force of parallel which is the line up the ramp
\[F//=fg(sinx)\]
that is the more important one. the only unknown value is mass
so you know your force of parallel is 591 pounds (i always used newtons). your angle is 17 degrees to get Fg you would M*9.8=Fg. does that help?

Answer 11

ya but how do i put the equation together

Answer 12

591=(m(9.8))(sin(17))

Answer 13

whats m for

Answer 14

mass. i dont know why your using pounds and weight, but i never have in physics

Answer 15

you should know that gravity accelerates you perpendicular to the earths surface at 9.8 m/s^2 and mass times acceleration=force.

Answer 16

591=(m(9.8))(sin(17)) how do i solve this

Answer 17

591=(m(9.8))(sin(17))

Answer 18

sir plz

Answer 19

how do i solve this problem

Answer 20

i donno why but that link gives an interesting way to come up with the solution. ive never seen this solution in physics. let me check this problem out real fast. because physics you have to use the right units for it to work out

Answer 21

so the way they solve it is
W=591/cos(73)

Answer 22

yes

Answer 23

so what is your problem?

Answer 24

a force of 591lb is required to pull a boat up a ramp inclined at 17.0 degreee with the horizontal how much does the boat weight

Answer 25

i know that. do you not know what cos 73 is?

Answer 26

.2923717047

Answer 27

ok now what is 591/.29

Answer 28

2037.931034

Answer 29

sounds like you have it to me

Answer 30

so the answers is 2038

Answer 31

sir its it right 2038

Answer 32

according to that page you linked it is and as long as noone cares about sig figs. ive never solved a vector problem like that with such disregard to units before so i couldnt swear to it. i just followed the link you gave me.

Answer 33

oh k so the final it 2038 thanks you
