Suppose you have a pendulum clock which keeps correct time on earth(acceleration due to gravity = 1.6 m/s2). for ever hour interval (on earth) the moon clock:

a) (9.8/1.6)h
b) 1 h
c) the square root of 9.8/1.6 h
d) (1.6/9.8)h
e) the square root of 1.6/9.8 h

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?

Aheavy piece of hanging sculpture is suspended by a90-cm-long, 5.0 g steel wire. when the wind blows hard, the wire hums at its fundamental frequency of 80hz. what is the mass of the sculpture?
