Question: A. A tractor pulls a 150 kg rock to the right with a force of 1200 N against a force of friction of 750

A. A tractor pulls a 150 kg rock to the right with a force of 1200 N against a force of friction of 750 N [left]. Calculate the force of gravity on the rock and the normal force of the ground on the rock. Draw a FBD of the rock, and determine the magnitude and direction of the net force acting on the rock. Use Newton's second law to find the acceleration of the rock. B. A crane pulls upwards on a 250 kg bin with a force of 3200 N. Calculate the force of gravity on the bin. Draw a FBD of the bin. Ignore any air resistance, and determine the magnitude and direction of the net force acting on the bin. Use Newton's second law to find the acceleration of the bin.
