A truck of mass 2000 ~kg is moving along a circular path having radius of curvature 10 ~m . if the banking angle is 39^ , then the maximum permissible speed of the truck is (Acceleration due to gravity =10 ~ms ⁻² , take 39^ =0.81)
Options
- A14 ~ms ⁻¹
- B5 ~ms ⁻¹
- C18 ~ms ⁻¹
- D9 ~ms ⁻¹
Correct answer
D. 9 ~ms ⁻¹
Step-by-step solution
Mass of truck, M=2000 kg Radius of curvature, R =10 ~m Banking angle, a=39^ , 39^ =0.81 Maximum speed is given as: aligned & v= R g = R g & v= 10 10 0.81 & v=9 ~m / s aligned
