Question

How do I find minimum force required to prevent a ball weighing 29.6 lbs from rolling down a ramp which is inclined 14.9° with the horizontal?

Answer 1

by posting it on physics group

Answer 2

this is trig

Answer 3

\[mgsin \theta\]

Answer 4

mg=29.6 in this instance correct?

Answer 5

no

Answer 6

m=29.6

Answer 7

so whats gravity?

Answer 8

g=32 feet/sec^2

Answer 9

is that a universal formula?

Answer 10

no

Answer 11

so how did you find gravity?

Answer 12

it is a genralised value

Answer 13

so (29.6)(32^2)sin14.9 will give me stopping power?

Answer 14

I didnt realize it was a vector scenario, I think I have it figured out thanks for your help though.
