Amissile is fired from a jet flying horizontally at mach 1 (1100 ft/s). the missile has a horizontal acceleration of 1000 ft/s 2 . calculate its horizontal velocity at 10.0 seconds after it is fired. (assume constant acceleration of the missile throughout its flight.)

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 acceleration of a spaceship that is initially at rest and then speeds up to 220 m/s in 20 seconds
