Problem 4: A jet airliner movin
102 mi/h in a
nitiaily at 3.00 x 102 mi/h due east enters a region where the wind is blowing 1.00 x
30 0° north of east.
a)
Find th components of the velocity of the jet airliner relative to the air, VA
b) Find the components of the velocity of the air relative to Earth,
c)write an equation relating the velocities
d)What are the speed and direction of the aircraft relative to the ground?

The slope of a good speed time indicates ? a. velocity b. acceleration c. direction d. speed

During spring semester at mit, residents of the parallel buildings of the east campus dorms battle one another with large catapults that are made with surgical hose mounted on a window frame. a balloon filled with dyed water is placed in a pouch attached to the hose, which is then stretched through the width of the room. assume that the stretching of the hose obeys hooke's law with a spring constant of 89.0 n/m. if the hose is stretched by 5.80 m and then released, how much work does the force from the hose do on the balloon in the pouch by the time the hose reaches its relaxed length? unitst 3 number-1497 the tolerance is +/-5% open show work click if you would like to show work for this question:
