A projectile is launched straight upward from Earth's surface at the North Pole. For Earth's radius at the North Pole, use
RE, NP = 6.36 ✕ 106 m.
(a) Ignoring air resistance, find the maximum altitude of the projectile above Earth's surface if the launch speed is
2.31 ✕ 103 m/s. m

A satellite is in a circular low Earth orbit at an altitude of
352 km
above the equator's surface. For Earth's radius at the equator, use
RE, eq = 6.38 ✕ 106 m.
(b) Assuming only the force of Earth's gravity acts on the satellite, determine the smallest required change in the satellite's speed if it is to escape Earth's gravity and never return. m/s

1. consider the case in which air fills air shocks on a truck trailer. the pressure in the shocks is 2 mpa. the temperature is 300 k. the diameter of the shock piston is 10 cm and the initial length of the cylindrical cavity containing the compressed air is 40 cm. a. the truck is gradually loaded over a period of a day in a static setting. the temperature is held constant for the atmosphere and thus for the gas shock. calculate the compressibility of the air in the shock for this condition when the truck is initially being loaded. b. if the shocks were loaded in a dynamic setting by driving over bumps, what would be the compressibility? state your assumption. c. what is the initial load on the shock if the shock is in an atmospheric 100 kpa? d. if the shock is compressed using the process described in part a, and the air shock compressed air cavity length decreases to 20 cm, what is the additional load applied to the shock?

What is the magnitude of the resultant vector round your answer to the nearest tenth

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line
