Antiballistic missiles (ABMs) are designed to have very large accelerations so that they may intercept fast-moving incoming missiles in the short time available. What is the takeoff acceleration (in m/s2) of a 10,000 kg ABM that expels 175 kg of gas per second at an exhaust velocity of 2.45 ✕ 10^3 m/s? (Enter the magnitude.)

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 (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...

6. Traumatic brain injury such as concussion results when the head undergoes a very large acceleration. Generally, an acceleration greater than 1000 ms lasting for at least 1 ms will cause traumatic injury. Suppose a small child rolls off a bed that is 0.42 m above the floor. Assume the child remains horizontal during the fall to the floor. If the floor is hardwood, the child's head is brought to rest in a distance of approximately 2.0 mm Note that...
