Academics

A coin is tossed upward with a velocity of 20 m/s near the earth surface. The coin will come to rest after exact 10 second. If the coin was tossed up with same initial velocity on planet, after 10 seconds, it would still be moving upwards at nearly 15 m/s. The magnitude of the gravitational field near the planet is what fraction of the gravitational field near the earth's surface.
