A car is moving with speed `30m//sec` on a circular path of radius 500 m . Its speed is increasing at the rate of , `2m//sec^(2)`, What is the acceleration of the carA. `2 ms^(-2)`B. `2.7ms^(-2)`C. `1.82 ms^(-2)`D. `9.82ms^(-2)` |
|
Answer» Correct Answer - B Net acceleration in non-uniform circular motion, `a=sqrt(a_(t)^(2)+a_(c)^(2))` `=sqrt((2)^(2)+[(900)/(500)]^(2))=2.7 ms^(-2) ` |
