Question

A horse of mass 187 kg pulls a cart of mass 200 kg. The acceleration of gravity is 9.8 m/s2 . What is the largest acceleration the horse can give if the coefficient of static friction between the horse’s hooves and the road is 0.612? Answer in units of m/s2.

Answer 1

net force=mass*a
pulling-friction=mass*a

assuming the cart has no friction..
horsemass*g*.612-0=(187+200)a
solve for a.
