Concept explainers

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.

Could someone please explain? Thank you.
You throw a ball straight up. The ball leaves your hand at a height of 2.00 m above the ground with a speedof 20.0 m/s (~45 mph). Ignore air resistance and use g = 10.0 m/s2. You can use a spreadsheet but show asample calculation for the velocity and the position at t = 1.5 s.
Dont round off thanks.
