A rescue helicopter drops a 10 kg package of emergency supplies to hikers stranded in the rocky valley. The chopper velocity has horizontal component due east at 1 m/s and a vertical component 2 m/s. The pilot drops the package from a height of 30 m above the ground. The acceleration due to gravity is 9.81 m/s2.
- Where does the package strike the ground relative to the point where it was released?
- What is the kinetic energy of the package as it strikes the ground?
- If, instead of dropping, to avoid the breakage, the package was lowered on a 29 m long rope and started oscillating like pendulum, what would be its period?

PRACTICE IT Use the worked example above to help you solve this problem. An Alaskan rescue plane drops a package of emergency rations to stranded hikers, as shown in the figure. The plane is traveling horizontally at 37.0 m/s at a height of 1.50x 102 m above the ground. (a) Where does the package strike the ground relative to the point at which it was released? 04.71m (b) What are the horizontal and vertical components of the velocity of the...
