Abottle rocket experiences a 500 n force to the right and 300 n of air resistance to the lefta box experiences a 20 n force to the left and a 19 n frictional force to the righta box experiences a 20 n force to the left and two different 8 n forces to the righta car experiences a 300 n force to the right from the engine and separate 150 n force due to air resistance to the left. a rope experiences three 400 n forces to the left and three different 410 n forces to the righta skateboard is pushed up a hill with a 90 n force to the left and experiences a gravitational force of 100 n to the right will accelerate to the left will accelerate to the right will not accelerate

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’s #16 asking me and how do i solve it?

If the spring constant k of a pogo stick is 3500 n m and the weight of the person on the pogo stick is 700 n, how much is the spring in the botom of the pogo stick compressed?
