Pushing at an angle up an inclined plane

  • #1
1. You are pushing a box of mass 18kg with a force of 239 N at 34.7 degrees below the horizontal. The box is on an inclined plane at angle 15 degrees above the horizontal. What is the acceleration of the box up the ramp?



2. F=ma
Fpush-Fgx = ma




The Attempt at a Solution


Fgx = (Fg)(sin(15))
Fpush = (Fg)(cos(34.7))

Fpush - Fgx = ma
145.174 N - 45.702 N = (18kg)(a)
a = 5.5262 m/s/s
