Question

obtain the formula
for maximum
safe
Speed of vehicle on
level curved woad.​

Answer 1

Explanation:

Frictional force = Centripetal force

Mmg = mvma^2x/R

Vmax^2= MgR

Vmax = ✓ Mgr

work done = f.dx

F= ma = mv.dy/dx

workdone = ma.dx=(mv dy/dx). dx

= m. vdy/dx.dx

= mv.dy

=m v^2/2

= 1/2 mv^2
