A man with his hands in his pocket is standing in a bus , which is taking a turn in a horizontal curve of radius 50 m , with a speed of 7 m/s far from the vertical must he lean to keep his balance ?

A

`theta = tan ^(-1)(0,2)`

B

`theta =tan ^(-1) (0.15)`

C

` theta = tan ^(-1)(0.1)`

D

`theta = tan ^(-1) (0.50)`

Text Solution

Verified by Experts

The correct Answer is:
C
To keep his balance , the man must lean through an angle ` theta ` where ` tan theta =(v^(2))/( rg) = ( 7xx7)/(50xx9.8)=(49)/( 400) = 0.1`
` therefore theta = tan ^(-1) (0,1) `
