A car speeds up in a circular path. Which of the following figures illustrates the acceleration of the car?A. B. C. D. |
|
Answer» Correct Answer - b Net acceleration: `a=sqrt(a_(c)^(2)+a_(t)^(2))` `=sqrt(((v^(2))/R)^(2)+a_(t)^(2))` As v increases, a also increases. So size of arrow should be increasing and angle between velocity and acceleration should be acute. |
