The cars on a theme park ride each have a mass of 500 kg and travel around a vertical loop of diameter 20m.(adsbygoogle = window.adsbygoogle || []).push({});

What is the minimum speed at which the cars must enter the loop in order to remain in contact with the track and What will then be the maximum reaction of the track?

M=mass

g=gravity

r=radius of loop

i dont know how to work out the mimimum speed required becuase there is no time value or angular acceleration given.

to work out the maximum reaction

Square root of (MgXr)

500X9.81=4905

4905X10=49050

square root of 49050 = 221.472 newtons (not sure on the forumla though)
