Question

A jet plane is travelling with a constant speed of 1080 kmph. The radius of the circle in which the
plane flies with a acceleration of 3g is [ ]
a) 2km b) 3km c) 30km d) 30m

Answer 1

Answer:

Ask to the pilot of that plane

Answer 2

Explanation:

B

Solution

V=1080kmph,a=3g,r=?

=60×5m/s

=3×10=30m/s2

a=v2r

⇒r=v2a=60×5×60×530

∴r=3000m

r=3km
