Hi, I'm new to this forum, I'm taking honors Physics this year and I'm not sure of what I'm doing in this homework problem...
"Joe pushes on the handle of a 10 kg lawn spreader. The handle makes a 45 degree angle with the horizontal. Joe wishes to accelerate the spreader from rest to 1.39 m/s/s in 1.5 seconds. What force must Joe apply to the handle? Neglect friction."
I've done part of it but I'm not sure whether its right...
F= (10 kg)(1.39 m/s/s)
F= 13.9 N
But where does the 45 degrees come in? Am I completely off track?
Thank you,
Kate
