(c) A small object was found to drop above the surface of a big planet with no initial
velocity and it fell 13.5 m in 3 s. If the radius of the planet is 5.82 x 10° m, calculate
the small object's acceleration during the fall and the mass of the big planet.
If the radius of earth were to shrink by one percent, its mass
remaining the same, the acceleration due to gravity on the
earth's surface would
