1 Horse Power = 746 Watts
P = W/t
P = DKE/t = 1/2m(V22 - V12)/t
95 km/hr[1000m/km][hr/3600sec]
6.6 x 104 W or 88 hp
1 Horse Power = 746 Watts
P = W/t
P = Fd/t
F = [mgsinq]d/t
P = 1047 W P = 1.0 x 103 W
P = Fd/t
v=75 km/hr[1000m/km][hr/3600s] v = 21 m/s P = Fv 1 Horse Power = 746 Watts P = 746 W[120 hp] P = 9.0 x 105 W Fnet = -mgsinq - f + Fcar = 0
Fcar = mgsinq + f
P = Fv
P = [mgsinq + f]v
