A cart of mass 1000 kg is pulled by a horse of 200kg. The coefficient of friction between them and ground is 0.2. Calculate the force required to produce acceleration of 2 m/s^2 in the cart??'
The net force required to give the cart acceleration of
The friction between the cart and the ground will be in the opposite direction of the pull on the cart.
#F_"net" = 2000 N = F_"pull" - F_f = F_"pull" - 1960N
... Assuming level ground.
I hope this helps,
