The Following Equation Was Obtained by Solving a Physics Problem

Multiple Choice

The following equation was obtained by solving a physics problem: $$\frac { \left( 16.0 \frac { \mathrm { m } } { \mathrm { s } } \right) ^ { 2 } } { ( 75.0 \mathrm {~m} ) \left( 9.80 \frac { \mathrm { m } } { \mathrm { s } ^ { 2 } } \right) } = \tan 19.2 ^ { \circ }$$ The best physical representation of the situation is

A) A car traveling at 16.0 m/s is 19.2 $\degree$ into a turn of a quarter circle on a level road.
B) A mass on a string that is originally horizontal has fallen to where the angle between the string and the vertical direction is 19.2 $\degree$ .
C) A mass on a string originally horizontal has fallen 19.2 $\degree$ from the horizontal direction.
D) A car traveling at 16.0 m/s is on a circular curve banked at 19.2 $\degree$ .
E) A car traveling at 16.0 m/s and going over a semicircular mountain-top road is 19.2 $\degree$ down from the top.
