You are driving your car, and the traffic light ahead turns red. you apply the brakes for 2.26 s, and the velocity of the car decreases to + 5.43 m/s. the carâs deceleration has a magnitude of 2.78 m/s2 during this time. what is the carâs displacement? x =

The density of a substance is 4.0 g/cm3. if a sample of the substance has a volume of 25 cm3 then what is the mass

Very large accelerations can injure the body, especially if they last for a considerable length of time. one model used to gauge the likelihood of injury is the severity index ( ), defined as =/ . in the expression, is the duration of the accleration, but is not equal to the acceleration. rather, is a dimensionless constant that = the number of multiples of that the acceleration is equal to. in one set of studies of rear-end collisions, a person's velocity increases by 13.7 km/h with an acceleration of 36.0 m/s2 . let the + direction point in the direction the car is traveling. what is the severity index for the collision?

Why is it important always to use horizontal bars in unit fractions when performing unit conversions?
