1. A dog pulls on a 1.5 kg bone parallel to the ground with a force of 7.0 N to the left and the boy is pulling on the bone parallel to the ground with a force of 3.0 N to the right. What is the acceleration of the bone, don't forget direction?

1. What is the force required to give a 45.0 N suitcase an acceleration of 3.6 m/s²?

1. A block has two forces on it. One force is 15 N going north and the other is 22 N going east. What is the overall force pushing on the block with magnitude and direction?

1. A boy pushing with a 12.5 N on a box on a frictionless surface at a 25^o angle to the horizontal accelerates at a rate of 4.53 m/s². What is the mass of the box?

1. You are standing on a scale in an elevator on the 4th floor of the science building. As the elevator begins to descend to the first floor, you notice the scale reads only 85% of your weight. What is the acceleration of the elevator during the period of time?

1. A block with a mass of 7.5 kg is held in equilibrium with a force pushing parallel to a 35^o ramp. Find the F_N and the force holding the block. Draw a force diagram and label the forces.

A clerk moves a 15 kg box down an aisle with a force of 155 N at an angle of 35.0^o to the horizontal. The coefficient of kinetic friction between the box and the floor is 0.35. Find the acceleration of the box.
