1. Cassidy Reese is showing off her skydiving skills and testing the difference between shallow and deep braking configurations of her parachute. After a period of free fall, she deploys her chute and sets her parachute to shallow braking conditions where she has a velocity of vs = 12.0i hat − 4.5j m/s. After a period of time, Δts, she changes the setting to deep braking conditions, vd = 6.0i hat − 1.5j m/s, for the remainder of her dive. The simulation displays her trajectory for various Δts displaying the displacement in the x- and y-directions for both parts of her journey. Here, xs and ys are the x- and y-components of her displacement while the parachute is configured in the shallow braking conditions, and xdand yd are the components of her displacement while in the deep braking configuration.2. Cassidy decides to use her vast knowledge of physics to calculate what Δts to use if she wants to travel half the height (y-direction distance) in shallow braking and half the height in deep braking conditions. She uses the information about the velocities in the y-direction and the total y-displacement of 2400 m to calculate what Δts to use in order for the y-displacement to be the same in each part of her motion.1. Y velocity for shallow breaking 4.5m/s2. Y velocity in deep breaking 1.5m/sA. Total X-displacement from part 1 = 7800mB. Total displacement from part 1: 3840C. Total time part 1: 1000s (300s shallow) (700s deep)

Air is held within a frictionless piston-cylinder container, which is oriented vertically. the mass of the piston is 0.45 kg and the cross-sectional area is 0.0030 m2. initially (state 1) the pressure of the gas is sufficient to support the weight of the piston as well as the force exerted by the atmospheric pressure ( 101.32 kpa). the volume occupied by the air within the cylinder in state 1 is 1.00 liter. one end of a spring (with spring constant k = 1000 n/m) is attached to the top of the piston, while the other end of the spring is attached to a stage that can move vertically. initially the spring is undeflected and therefore exerts no force. then the stage is then moved quasistatically downward a distance of 10.0 cm, at which point the system reaches state 2. the piston-cylinder is not insulated; rather it remains in diathermal contact with the surroundings, which are at a constant temperature of 300 k. what is the change of pressure within the container?
