Answer:
The maximum speed of car will be 20.5m/sec
Explanation:
We have given mass of car = 1100 kg
Radius of curve = 82.3 m
Static friction [tex]\mu _s=0.521[/tex]
We have to find the maximum speed of car
We know that at maximum speed centripetal force will be equal to frictional force [tex]m\frac{v^2}{r}=\mu _srg[/tex]
[tex]v=\sqrt{\mu _srg}=\sqrt{0.521\times 82.3\times 9.8}=20.5m/sec[/tex]
So the maximum speed of car will be 20.5m/sec
Answer:20.51 m/s
Explanation:
Given
Mass of car(m)=1100 kg
radius of curve =82.3 m
coefficient of static friction([tex]\mu [/tex])=0.521
here centripetal force is provided by Friction Force
[tex]F_c(centripetal\ force)=\frac{mv^2}{r}[/tex]
Friction Force[tex]=\mu N[/tex]
where N=Normal reaction
[tex]\frac{mv^2}{r}=\mu N[/tex]
[tex]\frac{1100\times v^2}{82.3}=0.521\times 1100\times 9.81[/tex]
[tex]v^2=0.521\times 9.81\times 82.3[/tex]
[tex]v=\sqrt{420.63}=20.51 m/s [/tex]
