A stone is thrown vertically upward with an initial velocity of 40 m/s. Taking g = 10 m/s², find maximum height reached by the stone. What is the net displacement and total distance covered by the stone?

Calculate the force of gravitation between the earth and the sun, given that the mass of the earth = 6 x 10²⁴ kg and of the sun = 2 x 10³⁰ kg. The average distance between the two is 1.5 x 10¹¹ m.

A stone is released from the top of a tower of height 19.6 m. Calculate its final velocity.

A ball thrown up vertically returns to the thrower after 6 s. Find:
(a) the velocity with which it was thrown up,
(b) the height, and
(c) its position after 4 s.

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. Find when and where the two stones meet?
