Kinematics Question 717

Question: An aircraft executes a horizontal loop with a speed of 150 m/s with it’s, wings banked at an angle of 12o . The radius of the loop it’s (g=10m/s2) [Pb. PET 2001]

Options:

A) 10.6 km

B)9.6 km

C) 7.4 km

D)5.8 km

Show Answer

Answer:

Correct Answer: A

Solution:

The angle of banking, tanθ=v2rg

therefore tan12=(150)2r×10

therefore r=10.6×103m=10.6km
