Question

which of the following books are accelerating? select all that apply. a heavy textbook that a student is lifting straight up at a constant speed a partially finished coloring book that a girl is waving in a circle an old cookbook that is lying motionless in a kitchen cabinet

Explanation:

Acceleration occurs when there is a change in velocity (speed or direction). An old cookbook lying motionless has zero acceleration. A coloring - book being waved in a circle has acceleration due to changing direction. A textbook being lifted straight up at a constant speed has no acceleration in the horizontal direction but has acceleration in the vertical direction during the lift (when starting and stopping the lift, and if considering gravity).

Answer:

A partially finished coloring book that a girl is waving in a circle, a heavy textbook that a student is lifting straight up at a constant speed
