A woman pushes a lawn mower with a con
stant force of 112 Newtons at an angle of
37 with respect to the horizontal. The lawn
mower moves at a speed of 20 cm/sec.
What is her power output? (1 hp = 746
Watts)

physics 
Damon,
v = .2 m/s
F = 112 cos 37
power = F v = .2 * 112 cos 37 Watts
to get HP divide by 746
