PISA Question-It is observed that a 1 point
body going vertically upward
decreases its speed by 10 m/s in
every 1 sec and finally its speed
becomes ‘O'(at highest point) and
then starts to fall by increasing its
speed 10 m/s after every 1 sec. (a)
What is the ratio of time of as3nt to time of desecent , when a body thrown up?​

Answer 1

Answer:

The magnitude of acceleration is taken place with g and second body has a downward acceleration with respective of g.

This denotes first body and utilize with same acceleration and no one is accelerating with respect to another.

The magnitude of acceleration is zero because there is no change in velocity by practical. it is ultimately 0 by perfect measurement.

Hence,

option a
