Homework Help: Force on object at angle to acceleration

  1. Sep 21, 2009 #1
    1. The problem statement, all variables and given/known data

    Joe pushes down the length of the handle of a
    10.5 kg lawn spreader. The handle makes an
    angle of 42◦ with the horizontal. Joe wishes to
    accelerate the spreader from rest to 1.35 m/s
    in 1.3 s.
    What force must Joe apply to the handle?
    Answer in units of N.

    2. Relevant equations
    I cant even figure out which equation to use :(

    3. The attempt at a solution

    Can you figure out what the acceleration should be based on what is given?

    If you can, then you can analzye all the Forces on the spreader and make sure that the net force is in the same direction as the acceleration. Then it just comes down to F=ma

    I can find acceleration, but not sure how else to finish it
