What is the first velocity of the car with one washer at
the 0.25 meter mark?
calculate the first and second velocities of the car with
one washer attached to the pulley, using the formulas
vi = 0.25 m/tı, and
u2 = 0.25 m/(t2-ti)
where t, and t2 are the average times the car took to
reach the 0.25 and the 0.50 meter marks. record these
velocities, rounded to two decimal places, in table e.
what is the second velocity of the car with one washer
at the 0.50 meter mark?
m/s

In which of the following cases is work being done on an object? question 2 options: pulling a trailer up a hill carrying a box down a corridor suspending a heavy weight with a strong chain pushing against a locked door

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?
