A bunch of keys was thrown directly upward by Macoy, who is looking out of the window, to be caught by Len-Len living on a room right above him. Unfortunately, Len-Len wasn't able to catch the keys and therefore the bunch of keys went straight to the ground. If Macoy gave the keys an upward speed of 3 m/s and the keys reached the ground after Macoy threw the keys upward in 4 seconds, c. What is the keys' acceleration when it reached its highest point?d. What is the keys' velocity when it reached its highest point?

How would I begin to solve this problem? In Example 2.6, we considered a simple model for a rocket launched from the surface of the Earth. A better expression for a rocket's position measured from the center of the Earth is given by y(t) = (RE3/2 + 3*(g/2)1/2 REt)2/3 where RE is the radius of the Earth (6.38 ✕ 106 m) and g is the constant acceleration of an object in free fall near the Earth's surface (9.81 m/s2). (a) Derive expressions for vy(t) and ay(t). (Use the following as necessary: g, RE, and t. Do not substitute numerical values; use variables only.)
