Question

. On a certain planet, a small stone tossed up at 15m/s vertically uploads takes 7.5s to return tothe
ground. What is the acceleration due to gravity on the planet?

Answer 1

Answer:

On a planet, when a small stone is tossed vertically upwards at 15 m/s, it takes 7.5 sec to return to the ground. Acceleration due to gravity (g) on the planet. Hence, the acceleration due to gravity on the planet (g) = a = -2 m/s², where negative sign shows that the stone is deacclerating or retarding.
