• 1.2 m/s

• 3.3 m/s

• 4.6 m/s

• 6.6 m/s

• 9.3 m/s

A mass is dropped from a height h above the ground, and freely falls under the influence of gravity, which graphs here correctly describe the displacement and velocity of the object during the time the object is falling? Consider the “up" direction to be positive. Assume the mass starts at the origin.

If all of the forces acting on an object balance so that the net force is zero, then;

• The object must be at rest.

• The object’s speed will decrease

• The object will follow a parabolic trajectory

• The object’s direction of motion can change, but not its speed.

• None of the above
