5) Are the statements below correct? a) 1. Considering two different ways in the figure to push two identical heavy boxes to move at a constant speed, both cases a) and b) experience the b) same kinetic friction force. 2. With the presence of kinetic friction, a brick pulled by gravity can still slide down an inclined plane at a constant acceleration. 3. If a round object undergoes pure rolling downhill on an inclined plane, the friction force exerts zero torque to the object.
