Question

A racing car is mov ing round a circular track
at a constant speed of 60 m S·I. The radius •.
of the track is500m. What is rhe ratio ofthe
centripetal force to the weight of the car?

Answer 1

0.02
0.73
1.2
71.0
one of these is the answer but idk which one

Answer 2

.73 is the answer. F=mv^2/r and W=mg . SO taking ratio of F and W as mentioned in the problem,we get F:W=v^2/r*g. F : W=.73 .

Answer 3

thank u

Answer 4

Centripetal force= mv^2/r and weight=mg
ratio=mv^2/r/mg=60*60/500/10
ans. 72.5

Answer 5

You are welcome.
