Homework Statement
Find the normal force on an object, 80kg, which is being pulled by a force of 4000N. A) Up at an angle of 50 degrees, B) Down at an angle of 70 degrees
Homework Equations
Fn = Fwcosx
Fp = Fwsinx
The Attempt at a Solution
A)
Fp = Fwsinx
Fp = 4000sin50 = 3064N
(80*9.8) - 3064 = -2280N = 2280N
B)
Fp = 4000sin70 = 3758.8N
(80*9.8) + 3758.8 = 4542.7N
Is this correct?
