Sean, an astronaut stands on the edge of a lunar crater and throws a Frisbee" horizontally with a velocity of 5.00 m/s. With no atmosphere on the moon the Frisbee " will not have any force
of lift so it will “fly” like a stone. The floor of the crater is 77.0 m below the astronaut. What
horiz ontal distance will the Frisbee™ travel before hitting the floor of the crater? (The
acceleration of gravity on the moon is 1/6th that of the Earth).

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?

Apair of 10μf capacitors in a high-power laser are charged to 1.7 kv.a. what charge is stored in each capacitor? b. how much energy is stored in each capacitor?
