Question

A car of mass $1500kg$ rounds a curve of radius $250m$ at $90km/h$. Calculate the centripetal force acting on it. (in $N$)

• A. $3600$
  
• B. $3750$
  
• C. $2511$
  
• D. $2366$
  

Answer 1

The correct option is B $3750$

Given that sped of car $v=90km/h=25m/s$

As we know centripetal force is given by

$\Rightarrow F_c=\frac{m{v}^2}{r}=1500\times \frac{{25}^2}{250}=3750N$
