Kenny gets sent to a distant planet of radius 6.0 x 10^5m, and he tries to find out how big the planet is by kicking a sphere of 0.4 kg. He kicks it (with respect to the ground) at an angle of 45o, with a speed of 30 m/s. If the sphere lands 6 seconds later, what is the mass of that planet? Remember, the gravitational acceleration for this planet isn't the same as Earth's!

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.
