An object with mass of 4 kg is thrown with initial velocity of 20 m/s from point A and
follows track of ABCD.
A) Determine YD.
B) Determine velocity of object at D. (CD = 5m) (20p)
C) Determine time required for object to reach ground. (20p)

Give an example for each of the following situations: 1) negative acceleration, but positive velocity 2) positive acceleration and positive velocity 3) positive acceleration, but negative velocity 4) negative acceleration and negative velocity 5) positive velocity and no acceleration
