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.

A man is running at speed Uman to catch a bus already at
a stop, as shown in (Figure 1). At t= 0, when he is a
distance d from the door to the bus, the bus starts

Inserting the formulas you found for man (t) and bus (t) into the condition man (tcatch) Tbus (tcatch), you obtain the
following:
abustcatch, or abust2atch - Umantcatch + d = 0.
Intuitively, the man will not catch the bus unless he is running fast enough. In mathematical terms, there is a constraint on the
man's speed Uman so that the equation above gives a solution for tcatch that is a real positive number.
Find Uman,min, the minimum value of Uman for which the man will catch the bus.
Express the minimum value for the man's speed in terms of abus and d.

Shown is the motion diagram for a rider on a Ferris wheel that was turning at a constant speed. The inset to the figure showed how to find the acceleration vector at the rightmost point. Use a similar analysis to find the rider’s acceleration vector at the leftmost position of the motion diagram, then at one of the highest positions and at one of the lowest positions. Use a ruler so that your analysis is accurate.
