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 (SI), defined as SI = as21. In the expression,ns the duration of the accleration. but a is not equal to the acceleration. Rather, a is a dimensionless constant that equals the number of multiples of g that the acceleration is equal to. In one set of studies of rear-end collisions,...
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 (SI), defined as SI = a521. In the expression, t is the duration of the accleration, but a is not equal to the acceleration. Rather, a is a dimensionless constant that equals the number of multiples of g that the acceleration is equal to. In one set of studies of...
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 (??SI), defined as ??=?5/2?SI=a5/2t . In the expression, ?t is the duration of the accleration, but ?a is not equal to the acceleration. Rather, ?a is a dimensionless constant that equals the number of multiples of ?g that the acceleration is equal to. In one set of studies of rear-end...
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 (ST), defined as SI2t. In the expression, is the duration of the accleration, but a is not equal to the acceleration. Rather, a is a dimensionless constant that equals the number of multiples of g that the acceleration is equal to. In one set of studies of rear-end collisions, a...
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 (S1), defined as S1 a2. In the expression, t is the duration of the accleration, but a is not equal to the acceleration. Rather, a is a dimensionless constant that equals the number of multiples of g that the acceleration is equal to. In one set of studies of rear-end...
1. Cheetahs can accelerate to a speed of 20.0 m/s in 2.50 s and can continue to accelerate to reach a top speed of 27.6 m/s. Assume the acceleration is constant until the top speed is reached and is zero thereafter. Let the +?+x direction point in the direction the cheetah runs. Express the cheetah's top speed ?top in miles per hour (mi/h)(mi/h) . vtop = Starting from a crouched position, how much time ?accel does it take a cheetah...
