A 46.9 kg crate resta on a horizontal floor, and a 71.9 kg person is standing on the crate. determine the magnitude of the normal force that (a) the flooe exerts on the crate and (b) the crate exerts on the person.

If a scuba diver descends too quickly into the sea, the internal pressure on each eardrum remains at atmospheric pressure while the external pressure increases due to the increased water depth. At sufficient depths, the difference between the external and internal pressures can rupture an eardrum. Eardrums can rupture when the pressure difference is as little as 35 kPa. What is the depth at which this pressure difference could occur? The density of seawater is 1025 kg/m2 Number: 20 Units:
A space probe in travelling in outer space with a momentum that has a magnitude of 3.39x10 krys. A retrorocket is fired to slow down the probe. It applies a force to the probe that has a magnitude of 1.55x10 N and a direction opposite to the probe's motion. It fires for a period of 8.41 s. Determine the momentum of the probe after the retrorocket ceases to fire. Number | Units: Click for List
