Answer:
a = 16 m/s²
Explanation:
The mass of the object, m = 200 kg
The radius of the circular motion, r = 4 m
The speed of the object, v = 18 m/s
The centripetal acceleration is given by the relation,
a = v²/r
Substituting the given values,
a = 18 / 4
= 16 m/s²
Hence, the centripetal acceleration of the object is, a = 16 m/s²
There is not enough information given to answer with. The force of gravity at the planet's surface depends on the planet's radius as well as its mass. The planet could have exactly the same mass as Earth has. But if it's radius is only 71% of Earth's radius, then gravity on its surface will be twice as strong as gravity on Earth.
