Homework Statement
Moving a 150kg fridge a 12m ramp with a rise of 2.4m. the mover pulls the ridge up with a constant force of 710 N. the acceleration due to gravity is 9.8 m/s^2
Homework Equations
W=Fs
F=ma
The Attempt at a Solution
I found out the angle of the ramp was by doing arcsin(2.4/12)= 11.536959 degrees
So I am trying to figure out which forces to split into two components using this angle.
which then i will plug into w=Fs
i set the x and y direction as the direction of the ramp so I split the force of gravity into two components.
i took 710N- Fg)x= Fnet
so i did 710-mgsin(11.536959)=416 N
then i multiplied that number by 12
and got 4992
is this correct if not can you lead me in the right direction
