“a 90.0 kg person rides a spinning amusement park ride that has a radius of 11.5 m. if the person’s tangential speed is 13.2 m/s, what is the magnitude of the centripetal force acting on the person? ”

Centripetal force = mass * centripetal acceleration. Centeipetal acceleration = (tangential speed )^2/ radius. So Centripetal acceleration a= v^2/ r = (13.2)^2/ 11.5 = 174.24/11.5 = 15.153 So Centripetal force = 90 * 15.1513 = 1363.77N

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.

That would be kinetic energy
