Your class is performing an experiment which involves dropping an object from a great height Your job is to minimize
the damage to the object. Use your knowledge of momentum, force, and collision time to complete the sentence,
using the drop-down menus.
While the change in
will remain the same during a collision, the force needed to bring an object to a
stop can be
if the time of the collision is

Which of the following is an example of units for speed

Water is siphoned from a large tank and discharges into the atmosphere through a 50-mm diameter tube. the end of the tube is b = 2.1 m below the tank bottom which is a = 7.4 m deep, and viscous effects are negligible. determine the maximum height h over which the water can be siphoned without cavitation occurring. atmospheric pressure is 101.4 kpa, and the water vapor pressure is 1.79 kpa (absolute)

Two identical stars with mass m orbit around their center of mass. each orbit is circular and has radius r, so that the two stars are always on opposite sides of the circle. (a) find the gravitational force of one star on the other. (b) find the orbital speed of each star and the period of the orbit. (c) how much energy would be required to separate the two stars to infinity?
