Answer 2

Answer:

Given :-

Initial velocity = 0 m/s

Acceleration due to gravity = 10 m/s

Time = 10 sec

To Find :-

Speed when hit ground and height of the table

Solution :-

Firstly we will use Newton first law for finding speed

v = u + at

v = 0 + 10 × 10

v = 0 + 100

Hence, speed of Ball is 100 m/s.

Let's find height

Here, we will use Newton third law

v² - u² = 2as

100² - 0² = 2 × 10 × s

10,000 - 0 = 20s

10,000 = 20s

s = 10,000/20

s = 500 m

Hence the height of table is 500 m
