Question

178. A stone is thrown upwards and it rises to a heigh
of 200 m. The relative velocity of the stone with
respect to the earth will be maximum at :
(1) Height of 100 m (2) Height of 150 m
(3) Highest point (4) The ground​

Answer 1

Answer:

hi dear !!

4. The ground

Explanation:

Relative velocity of the earth is Absolute velocity−velocity with respect to earth

We know the absolute velocity will decrease with time because gravity is opposing the upward motion so the absolute velocity will be maximum at two moments once just after projection and once just before hitting back so option is near ground. so the answer is

Answer 2

Answer:

The answer will be the ground as close as the stone comes to ground it's velocity increases
