(Figure 1)A relief airplane is delivering a food package to a group of people stranded on a very small island. The island is too small for the plane to land on, and the only way to deliver the package is by dropping it. The airplane flies horizontally with constant speed of 352 km/hour at an altitude of 625 m . The positive x and y directions are defined in the figure. For all parts, assume that the "island" refers to the point at a distance D from the point at which the package is released, as shown in the figure. Ignore the height of this point above sea level. Assume that the acceleration due to gravity is g = 9.80 m/s2 .
After a package is dropped from the plane, how long will it take for it to reach sea level from the time it is dropped? Assume that the package, like the plane, has an initial velocity of 352 km/hour in the horizontal direction.
If the package is to land right on the island, at what horizontal distance D from the plane to the island should the package be released?
What is the speed vf of the package when it hits the ground?
Express your answer numerically in meters per second.

In a truck-loading station at a post office, a small 0.200-kg
package is released from rest at point A on a track that
is one-quarter of a circle with radius 1.60 m (the figure (Figure
1) ). The size of the package is much less than 1.60 m, so the
package can be treated as a particle. It slides down the track and
reaches point B with a speed of 4.00m/s . From point
B, it slides on a level...

The good ship Beegull is travelling in perfectly calm seas on course for a small remote island, to carry out a wildlife survey. It is travelling at a speed (relative to the surrounding sea) of 40 km h−1 with a bearing of 55◦ . It is initially on course to enter harbour at the island assuming no change in the sea conditions. Unfortunately, unknown to the crew, a strong current arises of 15 km h−1 in the direction from north-west...
