Question

a horse has a power output of 7 hp when it pulls a wagon w/a force of 300n.what is the wagons velocity?

Answer 1

as we know that Power is the dot product of force and velocity,
P=F.V
for velocity rearrange equation

now come to question
given data is
P=7hp=745.699872 watt
F=300 N
V=?

P=F.V
V=P/F
V=2.4856 m/s

Hope u got the point
