An object with a mass of 5.0 kg accelerates at a rate of 2.0 m/s2 in the positive -direction when two forces are applied to it. One of the forces acts in the positive -direction with magnitude 12.0 N. Find the magnitude of the other force.
Two children push horizontally and in opposite directions on a wagon. The first child pushes the wagon forward with a force of 56.2 N, while the second child pushes with a force of 82.6 N. The motion of the wagon on the ground produces a 10.3 N friction force. The mass of the wagon is 38.5 kg. Assume that forward displacement of the wagon corresponds to positive values.
What is the resultant acceleration of the wagon?
What is the resultant acceleration of the wagon if the friction force is 18.6 N?
A sailboat that has a mass of kg is at sea. The wind is exerting a force on the boat’s sails of N in a direction north of east. There is an ocean current pushing on the sailboat toward the east with a force of N.
What is the magnitude of the acceleration produced by the resultant force on the sailboat?
At what angle north of east is the sailboat accelerated?
