11. Why will a sheet of paper fall slower than
Into a ball?
12. Gravitational force on the surface of the moon is only =
strong as gravitational force on the earth. What is the weight
in newtons of a 10 kg object on the moon and on the earth?
13. A ball is thrown vertically upwards with a velocity of 49 m/s.
Calculate
W the maximum height to which it rises.
(ii) the total time it takes to return to the surface of the earth.
14. A stone is released from the top of a tower of height 19.6 m.
Calculate its final velocity just before touching the ground.
15. A stone is thrown vertically upward with an initial velocity of
40 m/s. Taking g= 10 m/s2, find the maximum height reached
by the stone. What is the net displacement and the total
distance covered by the stone?
16. Calculate the force of gravitation between the earth and the
Sun, given that the mass of the earth = 6 x 102 kg and of the
Sun
1.5 x 101 m.
2 x 1030 kg. The average distance between the two is
17. A stone is allowed to fall from the top of a tower 100 m high
and at the same time another stone is projected vertically
upwards from the ground with a velocity of 25 m/s. Calculate
when and where the two stones will meet.
18. A ball thrown up vertically returns to the thrower after 6 s.
Find
182
(a) the velocity with which it was thrown up.
(b) the maximum height it reaches, and
(c) its position after 4 s.​

Answer 1

Answer:

Explanation:

The falling object is subjected to the opposition force from the air surrounding it and it is termed as air resistance.  Therefore, as the air resistance is more, the sheet of paper falls slower than one that is crumpled into a ball.
