Question

16 Caleulate the force of gravitation between the earth and the
Sun, given that the mass of the earth = 6x 1024 kg and of the
Sun = 2 1050 kg. The average distance between the two is
1.5 x 10 m.
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.​
