(a) impossible to determine
(b). the outside car
(c). the inside car
(d). they are the same​

Answer 1

Explanation:

ANSWER

For cars not to slide

centripetal force= centrifugal force

⇒μmg=

r

mv

⇒v=

μrg

A

v

A

=

1

×100×10

=10m/s

Total distance

=100π+2×100π

=300π

t=

speed

distance

=

10

300π

=30πsec

B

v

B

=

2

×200×10

=20m/s

Total distance

=200π+2×100π

=400π

time=

speed

distance

=

20π

400π

=20πsec

Car B completes its journey before Car A.

Answer 2

Answer:

c.INSIDE CAR

Explanation:

ANGULAR VELOCITY VARRIES INVERSELY TO RADIUS OF TRACK.It is clear path by inside car will have radius abit lesser.
