Solve Your Spiderman Problem with Expert Tips | Easy Help Available

[Bdurb]

ignore the "a 65 kg box..." i just stress myself out to a point where i can't think staight. Can someone explain the spiderman problem to me?

 

[jrab]

try using trig and angles to model each one

write out a force statement and it should help you visualize it better

See, i am almost certain there are very little if any calculations. Basically what is happening to the normal force with "spiderman" applying directional force. It all depends on the amount of force applied by spiderman and the gravitational pull on the box itself correct?

pretty much think using the vertical components to solve

Ok now i need help with the question on the bottom of the pic.

assuming that fg is pushing the box down then break fg into sin and cosine components like before and solve using ma=Fg-Ff

draw a FBD it will help

remember normal force is perpendicular and gravity is always 90 degrees relative to the ground

Thanks man!
