Example 5: An object is thrown vertically upward with an initial speed of 25 m/s from the ground. What is the height of the object 1.0 s before it touches ground?)




A body moves in a straight line with 10 m/s for first 6 seconds. Then it accelerates with 4 m/s2 for next 6 seconds. What is the average velocity?
