Question

Someone pls answer this question A racing car complete 5 rounds of a circular track in 2 minutes. find the radius of the track,if the car has uniform centripetal acceleration of π² m/s²
give best answer​

Answer 1

Answer:

r = 144 m

____________________________________

Time for 5  rounds = 2 minutes.

                               = 2 × 60

                              = 120 Sec.

∴ Time for one round ( T ) =

∴ Frequency , n =

centripetal acceleration =

we have to find out

r = ?

________________________________________

centripetal acceleration = r  

                                          = r

                                          =   r ×

∴ r  =  

∴ r  =  

     =  

     =  

∴ r =  144 m

∵ hence,

radius of the track = 144 m

Hope its help u
