Arocket, launched from the earth, shuts off its engines when its speed is 4.90 km/s.
it reaches a maximum altitude of 2570 km before it falls back to earth.

at what altitude did the rocket's engines shut off?

the mass and radius of the earth are 5.97 1024 kg and 6.37 106 m, respectively.

According to the tide table below what time of day will the highest tide occur?

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?
