13. the primary factor in decreasing the kinetic energy of an object is to: a. decrease the mass b. decrease the velocity c. decrease the stopping distance d. decrease the direction 14. kaitlyns law makes it illegal for any child, under what age, to be left alone in a vehicle, unless another child at least 12 years old accompanies them? a. 6 b. 8 c. 3 d. 4 15. a large diamond painted in a lane means: a. stopping, standing or parking is prohibited in this lane b. this lane may not be used, except by emergency vehicles c. this lane is reserved for special traffic d. this lane will become an entrance lane in a few hundred feet
Answer
# Brief Explanations:
13. The kinetic - energy formula is $KE=\frac{1}{2}mv^{2}$. Since velocity is squared, decreasing velocity has a more significant impact on reducing kinetic energy compared to decreasing mass.
14. Kaitlyn's Law makes it illegal to leave a child under 6 years old alone in a vehicle without a child 12 or older present.
15. A large diamond painted in a lane indicates that the lane is reserved for special traffic, such as high - occupancy vehicles.
# Answer:
13. B. Decrease the velocity
14. A. 6
15. C. This lane is reserved for special traffic
