The 24-lb space-shuttle orbiter touches down at about 228 mi/hr. at 181 mi/hr its drag parachute deploys. at 36 mi/hr, the chute is jettisoned from the orbiter. if the deceleration in feet per second squared during the time that the chute is deployed is -0.00034v2 (speed v in feet per second), determine the corresponding distance s traveled by the orbiter. assume no braking from its wheel brakes.

Asubmarine has a "crush depth" (that is, the depth at which water pressure will crush the submarine) of 250 m. what is the approximate pressure (water plus atmospheric) at this depth? (recall that the density of seawater is 1025 kg/m3, g = 9.81 m/s2, and 1 kg/(ms2) = 1 pa = 9.8692 10-6 atm.) a. 34.8 atm b. 24.8 atm c. 25.8 atm d. 7.8 atm

What is the rate of change in a objects position?

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?
