What is the formula for straight-line depreciation?

Back

The formula for straight-line depreciation is: y = -D*x + P, where D is the annual depreciation amount, x is the number of years, and P is the initial purchase price.

Front

How do you calculate the annual depreciation of an asset?

Back

Annual depreciation can be calculated by dividing the initial cost of the asset by its useful life in years.

Front

What is the drag factor in accident reconstruction?

Back

The drag factor is a coefficient that represents the friction between the tires and the road surface, used to calculate vehicle speed during skidding.

Front

How do you determine the minimum speed of a vehicle from yaw marks?

Back

Minimum speed can be determined using the formula: S = √(g * d * f), where g is the acceleration due to gravity, d is the distance of the yaw mark, and f is the drag factor.

Front

What is the relationship between stopping distance and speed?

Back

Stopping distance increases with the square of the speed; as speed doubles, stopping distance increases by a factor of four.

Front

How do you calculate the total stopping distance of a vehicle?

Back

Total stopping distance is calculated by adding the reaction distance (distance traveled during the driver's reaction time) to the braking distance (distance required to stop the vehicle once brakes are applied).

Front

What is the formula for calculating the length of a chord in a circle?

Back

The length of a chord can be calculated using the formula: L = 2 * r * sin(θ/2), where r is the radius and θ is the angle subtended by the chord at the center of the circle.

Front

What is the middle ordinate in relation to yaw marks?

Back

The middle ordinate is the perpendicular distance from the midpoint of the chord to the arc of the yaw mark, used in accident reconstruction to estimate speed.

Front

How do you find the salary per game for a player?

Back

Salary per game is calculated by dividing the total salary by the number of games played.

Front

What is the significance of rounding in measurements?

Back

Rounding is important in measurements to ensure precision and clarity, especially when reporting results in practical applications.
