Question

A man in a minivan rounds a circular turn at a constant speed. Which of the following would cause the minivan to experience less acceleration ?

• A. traveling faster
• B. traveling around a turn with a smaller circular radius
• C. traveling with more weight in the van
• D. traveling around a turn with a greater circular radius
• E. traveling the opposite direction around the same turn

Answer 1

The correct option is D traveling around a turn with a greater circular radius

$a=\frac{v^2}{R}$. So for the lesser acceleration the speed of the car should be less and the radius of curvature must be large. Correct answer is option D
