You slide down a steep slide at an amusement park. The slide is set up so that you are sitting on a blanket so that only the blanket is in contact with the slide. As you start to speed up, you get anxious about how fast you are going and push down with your hands on the blanket. What happens as you increase the force of your hands on the blanket?

a. Your acceleration decreases, but never goes to zero.
b. Your acceleration increases.
c. Your acceleration decreases and can go to zero if you push hard enough.
d. Your acceleration does not change.

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?

Which of the following are not typically included in the periodic table? a. atomic mass b. element symbol c. isotopes d. number of electrons
