Achild has a toy tied to the end of a string and whirls the toy at constant speed in a horizontal circular path of radius r. the toy completes each revolution of its motion in a time period t. what is the magnitude of the acceleration of the toy?

This is what i found on google “according to the collision theory, the following criteria must be met in order for a chemical reaction to occur: molecules must collide with sufficient energy, known as the activation energy, so that chemical bonds can break. molecules must collide with the proper orientation.” i hope this information you.

Iwould choose the same momentum because if they throw a baseball very light and not hard at all then doing it with a bowling ball won’t hurt that worse
