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 (SI), defined as SI = a a5/21. In the expression, t is the duration of the accleration, t. but a is not equal to the acceleration.

We did this problem in class (3.10) and the answer ended up being 1.35 m/s but I'm still confused with the steps taken to get that answer.
In an experiment to determine the viscosity of some oil, a ball is dropped into the oil. The position of the ball is given by the formula y(t)=A+Bt+Ce^−Dt, where y is given in m, and t is the time in s. At t=0, y(0)=0.07 m, the y component of the velocity is zero and the y component of the acceleration is ay(0)=0.015 m/s^2. As t approaches infinity, the y component of the velocity approaches vy(∞)=0.55 m/s. The problem asks you to find what A, B, C, and D are. I found that B = 0.55 m/s and I believe I can crack if I just knew what one more constant was. However, I am completely stumped.
In an experiment to determine the viscosity of some oil, a ball is dropped into the oil. The position of the ball is given by the formula y(t) = A + Bt +C e−Dt, where y is given in m, and t is the time in s. At t = 0, y(0) = 0.1 m, the y component of the velocity is zero and the y component of the acceleration is ay(0)= 0.04 m/s2. As t approaches infinity, the y component of the velocity approaches vy(∞) = 0.5 m/s. What is the value of A, C, and D? Please show work so I can understand.

You're an investigator for the National Transportation Safety Board, examining a subway accident in which a train going at 90 km/hkm/h collided with a slower train traveling in the same direction at 24 km/hkm/h . Your job is to determine the relative speed of the collision, to help establish new crash standards. The faster train's "black box" shows that it began negatively accelerating at 2.1 m/s2m/s2 when it was 52 mm from the slower train, while the slower train continued at constant speed. What do you report ?
The following conversions occur frequently in physics and arevery useful. (a) Use 1 mi = 5280 ft and 1 h = 3600 s to convert 60 mphto units of ft/s. (b) The acceleration of a freely falling object is 32 ft/s2.Use 1 ft = 30.48 cm to express this acceleration in units of m/s2.(c) The density of water is 1.0 g/cm3. Convert this density to units ofkg/m3.

Dr. John Paul Stapp was a U.S. Air Force officer who studied the effects of extreme acceleration on the human body. On December 10, 1954, Stapp rode a rocket sled, accelerating from rest to a top speed of 282 m/s (1015 km/h) in 5.00 s and was brought jarringly back to rest in only 1.40 s. Calculate his (a) acceleration in his direction of motion and (b) acceleration opposite to his direction of motion. Express each in multiples of g (9.80 m/s2) by taking its ratio to the acceleration of gravity.
