Question 5

Retarding frictional force, $f$, on a moving ball, is proportional to its velocity, $V$. Two identical balls roll down identical slopes (A & B) from different heights. Compare the retarding forces and the velocities of the balls at the bases of the slopes.

Accepted Answer

$f_A > f_B$ ; $V_A > V_B$

Answer

$f_A > f_B$ ; $V_B > V_A$

Answer

$f_B > f_A$ ; $V_B > V_A$

Answer

$f_B > f_A$ ; $V_A > V_B$
