1 point After being cut off, Billy accelerates at a rate of 12.3m/s2 for 455 m. As he

approaches the biker who cut him off, his velocity is a ludicrous 125 m/s.

What was his initial velocity?

33.3 m/s

66.6 m/s

99.9 m/s

122.2 m/s

Truck traveling west on the highway experiences an acceleration to the east. what could be the cause of this acceleration

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?

(1 point) match the differential equations and their vector valued function solutions. you may wish to multiply at least one solution out fully, to make sure that you know how to do it. you can get the other answers quickly by process of elimination and just multiply out one row element.
