Homework Statement
Person pushes down the length of the handle of a 12.1kg lawn spreader. The handle makes an angle 44.1 degrees with the horizontal. Person wishes to accelerate the spreader from rest to 1.33m/s in 1.7s. What forece must person apply to the handle?
Homework Equations
F=ma
I imagine a=Δv/Δt
The Attempt at a Solution
I started to find the average acceleration, using a =Δv/Δt. a = 0.78m/s^2
Plug and chug to F=ma and get 9.4N. This seems way too simple of a solution.
Should I carry on with this:
Fx=max
Fy=may
then just find the resultant of F.
Fx = -9.47
Fy = -118.58
Resultant F = 118.96N...that seems way too much?
