5) Are the statements below correct? 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 same kinetic friction force. 2. With the presence of kinetic friction, a brick pulled by gravity can no longer 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 tends to accelerate the translational motion of the object. 4. If a round object undergoes pure rolling downhill on an inclined plane, the friction force tends to accelerate the rotational motion of the object. 6) Consider a pure-rolling race where two objects are simultaneously released from the top of an inclined plane and roll down to a finish line. For each group below, answer which object will win the race or it will be a tie (A or \( \mathbf{B} \) or Tie). 1. A: \( 100 \mathrm{~g} \) solid cylinder with \( R=10 \mathrm{~cm} \) vs B: \( 200 \mathrm{~g} \) solid cylinder with \( R=10 \mathrm{~cm} \). 2. A: \( 100 \mathrm{~g} \) solid cylinder with \( R=10 \mathrm{~cm} \) vs \( B: 100 \mathrm{~g} \) solid cylinder with \( R=20 \mathrm{~cm} \). 3. A: \( 100 \mathrm{~g} \) solid cylinder with \( R=10 \mathrm{~cm} \) vs \( \mathbf{B}: 100 \mathrm{~g} \) solid sphere with \( R=10 \mathrm{~cm} \). 4. A: \( 100 \mathrm{~g} \) solid cylinder with \( R=10 \mathrm{~cm} \) vs B: \( 100 \mathrm{~g} \) hollow cylinder with \( R=10 \mathrm{~cm} \).
