Question

Example 5.
A boy projects a stone vertically upwards and catches it
back after 5 s. How high the stone goes and with what
velocity it was thrown? Also calculate the separation
between the highest point and the stone 4 s after it was
projected upwards.
Take g = 10 m/s​

Answer 1

Answer:

When a ball is thrown vertically upward, it continues upward until it reaches a certain position, and then it falls downward. At that highest point, its velocity is instantaneously zero.
