Question 83 of 87 · 2.0 marks

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.

1 $f_{A} > f_{B}; V_{A} > V_{B}$
2 $f_{A} > f_{B}; V_{B} > V_{A}$
3 $f_{B} > f_{A}; V_{B} > V_{A}$
4 $f_{B} > f_{A}; V_{A} > V_{B}$

Correct answer: Option 1
