A car is moving along a straight road while speeding up.d. A hockey puck slides along a smooth (i.e., frictionless) icy surface.e. A hockey puck slides along a rough concrete surface.f. A cockroach is speeding up from rest.g. A rock is thrown horizontally; air resistance is negligible.i. A rock is thrown horizontally; air resistance is substantial.j. A rock is dropped vertically; air resistance is negligible.k. A rock is dropped vertically; air resistance is substantial.Which situation or situations describe the motion shown in the motion diagram at point C?

FREE Expert Solution

At point C, we realize that the speed is increasing. 

We also realize that the object is thrown and the air resistance is almost negligible.
