In a study investigating the effect of car speed on accident
severity, the vehicle speed at impact was recorded for 5000 fatal
accidents. For these accidents, the mean speed was 42 miles per
hour with a standard deviation of 15 miles per hour. Assuming the
speeds are normally distributed, use the empirical rule to answer
the following:
a) About what percent of vehicle speeds were between 42 and 72
miles per hour?
b) About what percent of vehicle speeds were in excess of 57
miles per hour?
c) About what percent of vehicle speeds were below 12 miles
per hour?
d) About what percent of vehicle speeds were between 12 miles
per hour and 57 miles per hour?

During a study of accident survivability a crash-test dummy is
placed in a car. The vehicle is brought to a speed of 30.0 ??ℎ and
then collided with a stationary barrier. During the first part of
the study the upper torso of the dummy collides with the steering
wheel and rebounds from the wheel at the same speed in1⁄100 ?ℎ of a
second. During the second part of the study, in an identical car,
an airbag deploys and brings the...
After an accident, how do police determine the speed of which the car had been traveling?
After an accident, how do police determine the speed of which the car had been traveling? The formula, R(s) = 2V5s can be used to approximate the speed rate, R(S), in mph of the car that has left a skid (s) mark in feet.a) Using this formula how far will a car skid at 75 mph?

Study the following class definition:
class Car
{
public:
Car(double speed);
void start();
void accelerate(double speed);
void stop();
double get_speed() const;
private:
double speed;
};
Which of the following options would make logical sense in the
definition of the void accelerate(double speed)function?
Group of answer choices
this->speed = this->speed;
this->speed = speed;
this.speed = speed;
speed1 = this->speed;

The power delivered to the wheels of a vehicle (w) as a
function of vehicle speed (V) is given by: w = 0.01417[hp/mph2]V 2
+ 0.6300[hp/mph]V - 0.3937[hp] where power is in horsepower and
velocity in mph. The amount of heat rejected from the engine block
(qb) is approximately equal to the amount of power delivered to the
wheel (the rest of the energy from the fuel leaves with the exhaust
gas). The heat is removed from the engine by...

Reza is a 23-year-old male who was involved in a motor vehicle
accident. After the accident, he told the paramedics he felt
extreme pain under his rib cage. He was transported by ambulance to
the hospital, and the attending physician determined Reza had
ruptured his spleen during the accident. He was scheduled for
emergency splenectomy. Due to the severity of the injury, Reza had
to have “open surgery” to remove his spleen.
The surgery was a success. Reza was given...
