A stone is thrown vertically upward with an initial speed of 20 m/s. When it returns, it fall into a hole that is 6.0 m deep. What is the velocity of the rock (in m/s) when it hits the bottom of the hole? Use -9.80 m/s2 for the local acceleration due to gravity and assume no significant air resistance. Assume that the y axis is positive in the up direction.

An unsuspecting bird is coasting along in an easterly direction at 4.00 mph when a strong wind from the south imparts a constant acceleration of 0.200 m/s2 . If the wind's acceleration lasts for 3.10 s , find the magnitude ?r and direction ?θ (measured counterclockwise from the easterly direction) of the bird's displacement over this time interval. Assume that the bird is originally travelling in the +?+x direction and that there are 1609 m in 1 mi . ?= ? ?= ?
