Question

A racing car of total mass 600 kg travels in a circle

of radius 80 m at 30

1 ms

round a corner. Assume

that the track surface is horizontal. Calculate the

required frictional force.​

Answer 1

Answer:6750*10^3N

Explanation:The track is circular path but the surface of the track on which it rides is horizontal.

in a circular path, cetripetal force gies the friction for car to be on the track.

so,friction=m(v^2)/r

m(v^2)=600*10^3(30^2)

m(v^2)/r=[600*10^3(30^2)]/80

=6750*10^3N
