constant speed means pull force = drag force
if harness tension = T
then Pull force = T cos 20
Pull force - friction force = m a = 0
so
T cos 20 = 4000
up force from tension = T sin 20
there is no acceleration up
weight = m g = (200+300)(10) = 5000 N
net force up from snow = weight - tension component up = 5000 - T sin 20
Calculate the magnitude of each force acting on the sleigh. The friction force has a magnitude of 4000N. The sleigh has a mass of 200kg. The people and their luggage have a mass of 300kg. The harness makes a 20-degree angle with the horizontal. Assume the sleigh is moving at a constant speed. Use g=10m/s^2.
