Question

a donkey pulls a cart of mass 250 kg east across a rough road.the donkey pulls the cart with a force of 300N t. the total frictional force on the cart is 50N

calculate the resultant force on the cart
the acceleration on the cart

Answer 1

Resultant force; 300 – 50 = 250N in the pulling direction

Acceleration; F = ma so

250 (use the resultant force) = 250 X a

a = 250/250

acceleration = 1 m/s^2
