Question

a circular track of radius R is banked at an angle theta a vehicle negotiate the track was moving at a speed V1) draw a diagram to show all the forces acting on the vehicle2) drive an expression for the maximum safe Speed the vehicle can have on this track take ų the relevant coefficient of friction3) with what speed should the vehicle negotiate the track to minimise the wear of its tyres​

Answer 1

Answer:

in this photo you will got the answer please take it is write 10 line and rate to me

Answer 2

Answer:

Correct option is

C

[

cosθ−μsinθ

Rg(sinθ+μcosθ)

]

1/2

Here f is frictional force =μN

Force balancing in vertical direction- Ncosθ=mg+μNsinθ⟹N=

cosθ−μsinθ

mg

(1)

In horizontal direction- μNcosθ+Nsinθ=

R

mv

2

(2)

Solving both equations-

cosθ−μsinθ

mg

(μcosθ+sinθ)=

R

mv

2

by solving- v=

cosθ−μsinθ

Rg(sinθ+μcosθ)
